  2. Inseparability of science history and discovery

    Full Text Available Science is very much a logical progression through time. Progressing along a logical path of discovery is rather like following a path through the wilderness. Occasionally the path splits, presenting a choice; the correct logical interpretation leads to further progress, the wrong choice leads to confusion. By considering deeply the relevant science history, one might begin to recognize past faltering in the logical progression of observations and ideas and, perhaps then, to discover new, more precise understanding. The following specific examples of science faltering are described from a historical perspective: (1 Composition of the Earth's inner core; (2 Giant planet internal energy production; (3 Physical impossibility of Earth-core convection and Earth-mantle convection, and; (4 Thermonuclear ignition of stars. For each example, a revised logical progression is described, leading, respectively, to: (1 Understanding the endo-Earth's composition; (2 The concept of nuclear georeactor origin of geo- and planetary magnetic fields; (3 The invalidation and replacement of plate tectonics; and, (4 Understanding the basis for the observed distribution of luminous stars in galaxies. These revised logical progressions clearly show the inseparability of science history and discovery. A different and more fundamental approach to making scientific discoveries than the frequently discussed variants of the scientific method is this: An individual ponders and through tedious efforts arranges seemingly unrelated observations into a logical sequence in the mind so that causal relationships become evident and new understanding emerges, showing the path for new observations, for new experiments, for new theoretical considerations, and for new discoveries. Science history is rich in "seemingly unrelated observations" just waiting to be logically and causally related to reveal new discoveries.

METHODS: Seventy two diabetic patients were selected, but only 46 attended the research. The patients were chosen based on Family's Health Program medical registers. They were submitted to visual acuity examination and afterward to a questionnaire in order to evaluate their knowledge level about visual impairment. Then, they were submitted to a direct fundoscopic examination. Statistical studies were done based on Microsoft Excel and Bioestat 5.0 RESULTS: Diabetic retinopathy prevalence was about 19,5% (CI 95% between 8,1 and 31%; 13% showed non proliferative diabetic retinopathy and 6,5% showed proliferative retinopathy. In accordance with World Health's Organization criteria: 8,5% were considered blind and 8,9% with low vision at the moment of ocular examination. Seventy two percent of patients had previous knowledge that diabetes could cause visual reduction, but 80% didn't know the necessary exams to diagnose it and 65% never were previously submitted to ophthalmoscopy. CONCLUSION: Blindness prevention programs by diabetic retinopathy in Family Health Programs are justified considering that the retinopathy diabetic prevalence in assisted communities could be high, as was in this study. The improvement of patient knowledge about the vision threatening risk and ophthalmological exams can allow a better retinopathy diabetic control.

  14. Inseparability of colours through dynamical breaking of SUsub(C)(3)

    International Nuclear Information System (INIS)

    Werle, J.

    1983-09-01

    A class of feasible quark field models based on the assumption that the quarks are the only carriers of colours is discussed. The forces between quarks are described by local but non-linear interaction between quark fields. Such models are much closer than QCD to the - so far very successful - naive quark model with colours. It is shown that inseparability and localization of colours, which are two basic conditions of quark confinement, are of dynamical nature. In particular, inseparability is simply incompatible with rigorous SUsub(C)(3) invariance. Therefore, explicit dynamical SUsub(C)(3) breaking is proposed in such a form that makes only the white currents strictly conserved. The resulting field equations imply manifest inseparability of colours. (author)

As Graham points out, much of Frye's thought is focused on secular concerns, and, within that context, his dialectical and `suprahistorical' thinking is `post-partisan,' a feature which also signifies and explains Frye's appeal. Graham contends it is the thinking of William Blake......, specifically his conceptions of innocence and experience, which provides the inspiration for Frye's dialectical thinking. Graham systematically addresses the main areas of Frye's work: Blake's poetry, secular literature, education and work, politics, and Scripture. In following each of these themes......, The Necessary Unity of Opposites expertly clarifies Frye's dialectical thinking, while drawing attention to its structural connection to Blake, Frye's great preceptor....

    1980-01-01

    The unity of the basic forces of Nature and the unity of all basic matter form the main theme of this paper. Recent developments in the theory of fundamental particles are reviewed. The 'quark' concept is described. Conclusion is drawn that the proton, neutron, hyperon and the sigma particles belong to one Baryon family. The Lepton family of electrons, muons and pions is also described. The quantum numbers isospin, strangeness etc. are explained. The nature of the four different basic forces viz., gravity, weak, electromagnetic and strong forces are discussed. Arguments are presented to indicate that the differences in these forces are described at low energies and that at high energies of the order of 10 5 BeV the three forces electromagnetic, weak and strong, merge into one and the same force and at the same energies quarks and leptons interact universally exhibiting their oneness. The stability of the proton is discussed. Future trends are indicated. A fundamental substructure 'preon' is proposed. (A.K.)

  20. Theodor Waitz on psychic unity.

    Science.gov (United States)

    Jahoda, Gustav

    2014-06-01

    The tolerant stance on 'race' by prominent Enlightenment figures was followed in the 19th century by a powerful wave of biological racism. Many of its proponents took the view that human 'races' constitute separate species, and that most non-white ones are of inferior mentality. An early opponent of this claim was James Cowles Prichard, who used mainly missionary reports in seeking to refute it. Far more extensive work was undertaken by the Herbartian psychologist Theodor Waitz, who collected ethnographic material from all over the world. It was published in six volumes - the last two after his death by his former student Georg Gerland. Waitz aim was to demonstrate the 'psychic unity' of mankind. Initially extracts from the volume on African peoples are presented in order to show how he dealt with his material. The main focus is on his first volume entitled Introduction to Anthropology, in which he elaborates his general thesis. In it Waitz maintains, against the biological racists, that mankind is a single species. Furthermore he discusses the changes from savagery to civilization, attributing them to a combination of geography and history. He was followed by Adolf Bastian who, unlike Waitz, was a great traveller with personal experience of peoples all over the globe. Both firmly believed in the psychic unity of mankind, but Bastian's approach to psychology was very different.

    1983-01-01

    A single or multiphase boost chopper regulator operating with unity power factor, for use such as to charge a battery is comprised of a power section for converting single or multiphase line energy into recharge energy including a rectifier (10), one inductor (L.sub.1) and one chopper (Q.sub.1) for each chopper phase for presenting a load (battery) with a current output, and duty cycle control means (16) for each chopper to control the average inductor current over each period of the chopper, and a sensing and control section including means (20) for sensing at least one load parameter, means (22) for producing a current command signal as a function of said parameter, means (26) for producing a feedback signal as a function of said current command signal and the average rectifier voltage output over each period of the chopper, means (28) for sensing current through said inductor, means (18) for comparing said feedback signal with said sensed current to produce, in response to a difference, a control signal applied to the duty cycle control means, whereby the average inductor current is proportionate to the average rectifier voltage output over each period of the chopper, and instantaneous line current is thereby maintained proportionate to the instantaneous line voltage, thus achieving a unity power factor. The boost chopper is comprised of a plurality of converters connected in parallel and operated in staggered phase. For optimal harmonic suppression, the duty cycles of the switching converters are evenly spaced, and by negative coupling between pairs 180.degree. out-of-phase, peak currents through the switches can be reduced while reducing the inductor size and mass.

  7. Inseparability of Go and Stop in Inhibitory Control: Go Stimulus Discriminability Affects Stopping Behavior.

    Science.gov (United States)

    Ma, Ning; Yu, Angela J

    2016-01-01

    Inhibitory control, the ability to stop or modify preplanned actions under changing task conditions, is an important component of cognitive functions. Two lines of models of inhibitory control have previously been proposed for human response in the classical stop-signal task, in which subjects must inhibit a default go response upon presentation of an infrequent stop signal: (1) the race model, which posits two independent go and stop processes that race to determine the behavioral outcome, go or stop; and (2) an optimal decision-making model, which posits that observers decides whether and when to go based on continually (Bayesian) updated information about both the go and stop stimuli. In this work, we probe the relationship between go and stop processing by explicitly manipulating the discrimination difficulty of the go stimulus. While the race model assumes the go and stop processes are independent, and therefore go stimulus discriminability should not affect the stop stimulus processing, we simulate the optimal model to show that it predicts harder go discrimination should result in longer go reaction time (RT), lower stop error rate, as well as faster stop-signal RT. We then present novel behavioral data that validate these model predictions. The results thus favor a fundamentally inseparable account of go and stop processing, in a manner consistent with the optimal model, and contradicting the independence assumption of the race model. More broadly, our findings contribute to the growing evidence that the computations underlying inhibitory control are systematically modulated by cognitive influences in a Bayes-optimal manner, thus opening new avenues for interpreting neural responses underlying inhibitory control.

  9. Construction of Scaling Partitions of Unity

    Directory of Open Access Journals (Sweden)

    Ole Christensen

    2017-11-01

    Full Text Available Partitions of unity in ℝd formed by (matrix scales of a fixed function appear in many parts of harmonic analysis, e.g., wavelet analysis and the analysis of Triebel-Lizorkin spaces. We give a simple characterization of the functions and matrices yielding such a partition of unity. For expanding matrices, the characterization leads to easy ways of constructing appropriate functions with attractive properties like high regularity and small support. We also discuss a class of integral transforms that map functions having the partition of unity property to functions with the same property. The one-dimensional version of the transform allows a direct definition of a class of nonuniform splines with properties that are parallel to those of the classical B-splines. The results are illustrated with the construction of dual pairs of wavelet frames.

  18. Gnosticism, church unity and the Nicene Creed

    Directory of Open Access Journals (Sweden)

    C. F.C. Coetzee

    2008-07-01

    Full Text Available Gnosticism (derived from the Greek word “gnosis; knowledge” is the well-known phenomenon or movement which dates from the first centuries of church history. The teaching of Gnosticism questioned and/or contradicted the teaching of the church on some of the fundamental truths of Scripture. Apart from Gnosticism, the Early Church also had to deal with the heresy of Arianism. In the Nicene Creed, formulated by the councils of Nicea (325 AD and Constantinople (381 AD the universal or catholic church responded officially to the heresies of both Gnosticism and Arianism. In the final edition of the Nicene Creed we also find an article on the unity, holiness, catholicity and apostolicity of the church. Both Gnosticism and Arianism posed a serious threat to the unity of the church.   In our times we experience a revival of ancient Gnosticism, both pagan and “Christian”. This revival is also called the New Age or the Age of Aquarius. Within the framework of this new worldview, we are witnessing a rediscovery of gnosis. The discovery and publication of certain ancient gnostic texts like the Nag Hammadi Codices, play a significant role in this revival. Consequently the canon of Scripture is questioned or openly rejected and also the creeds based on that Scripture.   The Nicene Creed played a major and decisive role in preserving and maintaining the unity of the church on the basis of the truth of Scripture. This age-old creed is today just as relevant and important in proclaiming and confessing the true faith and preserving the true unity of the church.

How deep are the changes experienced by children, who are acquiring and learning their oral and written languages, using such media? On the other hand, despite globalization, the geometrical growth of science and technology brings with it a parallel lexical explosion: specific texts undermine the possibility of their comprehension by the outsider as if the text was written in a foreign language, and so, the unity of communication is broken and distortions may appear.

    In the Space Station Processing Facility (SSPF), the Unity connecting module, part of the International Space Station, is lowered to its new location in the SSPF. In the background, visitors watch through a viewing window, part of the visitors tour at the Center. As the primary payload on mission STS-88, scheduled to launch Dec. 3, 1998, Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time. In the SSPF, Unity is undergoing testing such as the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle, as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter, and the common berthing mechanism to which other space station elements will dock. Unity is expected to be ready for installation into the Shuttle's payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27.

    Full Text Available This descriptive-analytic study by method in the form of a library in the field of Sciences of Quran and Hadith and suggests a new theory on difference of views about the religious judgments. The main problem is in one hand, the Quran's recognition of the plurality of religions in some verses and in other hand,the other verses those can be seen on the negation of religious plurality. In light of certain verses in this issue, some of thinkers have raised under different titles such as Traditionalism or religious pluralism and the unity of religions and religious pluralism and so on. mentioned religions in Quran, are essentially same in the Islam and monotheism. Thus there are the consensus on essential unity of religions and disagreement onhistoric unity of religions that is a source of more disagreements and different issues. Quran has determined the "bestdispute" asa method of dealing with religious laws that requires faith to common elements that is the "Islam" , although the "bestdispute" in light of the transcendental unity. This means that "best dispute" is a line between practical and theoretical pluralism. Instead of denying the "people of the Book", you shouldtake "Astbqa on charity" or overtaking on virtues. The rule stated in the Qur'an can be call"penetration in religion" and through this we can have better understand of the Qur'an's emphasis on reinforcement the Torah and the Gospel. However It should not be as pluralists, we have means Islam as only a religion in other religions.according to the Qur'an, the Prophet is the witness of the Muslims and people of Islam are witnesses of other peoples. total of true and mystical interpretation of the verses with these verses that explain Muslim religious superiorityindicate that the teachings of Islam has started fromthe holy scriptures, but under the prestige and the testimony of the teachings of the Prophet can be searched.

    Suppose we are given an entangled pair and asked how well we can produce two entangled pairs starting from a given entangled pair using only local operations. To respond to this question, we study broadcasting of entanglement using a state-dependent quantum cloning machine as a local copier. We show that the length of the interval for probability-amplitude-squared α 2 for broadcasting of entanglement using a state-dependent cloner can be made larger than the length of the interval for probability-amplitude-squared for broadcasting entanglement using a state-independent cloner. Further we show that there exists a local state-dependent cloner which gives better quality copy (in terms of average fidelity) of an entangled pair than the local universal cloner

    Full Text Available The notion of partitions of unity is extremely useful as it allows one to extend local constructions on Euclidean patches to global ones. It is widely used in many fields in mathematics. Therefore, prolongation of this useful tool to another manifold may help constructing many geometric structures. In this paper, we construct a partition of unity on a fiber bundle by using a given partition of unity on the base manifold. On the other hand we show that the converse is also possible if it is a vector bundle. As an application, we define a Riemannian metric on the fiber bundle by using induced partition of unity on the fiber bundle.

    2017-07-01

    Abnormalities of the endosomal-lysosomal network (ELN) are a signature feature of Alzheimer's disease (AD). These include the earliest known cytopathology that is specific to AD and that affects endosomes and induces the progressive failure of lysosomes, each of which are directly linked by distinct mechanisms to neurodegeneration. The origins of ELN dysfunction and β-amyloidogenesis closely overlap, which reflects their common genetic basis, the established early involvement of endosomes and lysosomes in amyloid precursor protein (APP) processing and clearance, and the pathologic effect of certain APP metabolites on ELN functions. Genes that promote β-amyloidogenesis in AD (APP, PSEN1/2, and APOE4) have primary effects on ELN function. The importance of primary ELN dysfunction to pathogenesis is underscored by the mutations in more than 35 ELN-related genes that, thus far, are known to cause familial neurodegenerative diseases even though different pathogenic proteins may be involved. In this article, I discuss growing evidence that implicates AD gene-driven ELN disruptions as not only the antecedent pathobiology that underlies β-amyloidogenesis but also as the essential partner with APP and its metabolites that drive the development of AD, including tauopathy, synaptic dysfunction, and neurodegeneration. The striking amelioration of diverse deficits in animal AD models by remediating ELN dysfunction further supports a need to integrate APP and ELN relationships, including the role of amyloid-β, into a broader conceptual framework of how AD arises, progresses, and may be effectively therapeutically targeted.-Nixon, R.

  17. A new unity for angular measurements in strabismus

    Directory of Open Access Journals (Sweden)

    Harley E. A. Bicas

    2014-10-01

    Full Text Available The practical advantages of quantifying an angle by a ratio of linear lengths instead of arcs of circles has led to the definition of the prism-diopter, a conventional unity for numbering prisms and measuring strabismic deviations. However, a major inconvenience of using prism-diopter unities to express angular measurements is the non-linearity of the scale, which reaches an infinite value for the angle of 90º, then becomes negative, with decreasing magnitudes for increasing angles between 90º and 180º. As a consequence, arithmetical operations and comparisons of angles measured by such unities present errors of very great magnitudes. In order to retain the advantages of defining an angle by straight line dimensions but to diminish the severe inconveniences of this method, a new definition of the prism-diopter is proposed. Here, instead of defining the prism-diopter by the asymmetrical condition, the conception of this new unity is based on a geometrically symmetrical condition; that of the relationship of an isosceles triangle (where the leg is perpendicular to the bisector of the angle and the bisector itself . The condition of symmetry for the definition of the new unity represents a conceptual advance because it reproduces the already well accepted, conventional criteria for quantifying the value of a prism, that of its minimum deviation. Furthermore, it corresponds to the most commonly observed clinical conditions of binocular balance. The absolute differences between the unitary values of the prism-diopter and that of the new unity are negligible (0.0025%, but the scale of values expressed by the new unity is closer to the ideal scale of angular measurements.

    Workers in the Space Station Processing Facility close the access hatch to the Unity connecting module, part of the International Space Station, before its launch aboard Space Shuttle Endeavour on STS-88 in December. Unity will now undergo a series of leak checks before a final purge of clean, dry air inside the module to ready it for initial operations in space. Other testing includes the common berthing mechanism to which other space station elements will dock and the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter. The next time the hatch will be opened it will be by astronauts on orbit. Unity is expected to be ready for installation into the payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27. The Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time.

    Full Text Available What is information? This is the first question that information science should answer clearly. However, the definitions of information have been so diversified that people are questioning if there is any unity among the diversity, leading to a suspicion on whether it is possible to establish a unified theory of information or not. To answer this question, a system approach to defining information is introduced in this paper. It is proved that the unity of information definitions can be maintained with this approach. As a by-product, an important concept, the information eco-system, was also achieved.

    Directory of Open Access Journals (Sweden)

    P.J. Strauss

    2010-07-01

    Full Text Available The reformer John Calvin, born in 1509, considers discipline and unity as two essential aspects of the Christian church. According to him, the bond of church discipline is a way to unite church members in the truth of the Word and the Christian faith based thereupon. If discipline is exercised with exaggerated strictness and without compassion, tolerance and love, it can break the unity. Because church unity is essentially a unity of faith, or a unity in the truth of the Word, discipline can sever adulterated elements that threaten the unity from the church. Discipline, if correctly ap- plied, builds the unity of the church as a unity in religious truths.

Elaborated explanation in this paper is expected to result in a true understanding of this crucial issue, particularly the concept of religious pluralism in the discourse of Islamic studies. Ibn Arabi’ extensively  discusses religion in the sense of the “ideal” versus “historical” or “esoteric” versus “the exoteric”. Ibn ‘Arabi concludes that the absolute unity of religions may only occur within spiritual, ideal, or transcendental realm (or “esoteric”, which is beyond the formal form of religions. Hence, the transcendental unity of religions cannot be found in the formal form of religions nor in the shari’ah.[Artikel ini mengulas pandangan Ibn ‘Arabi’ mengenai wahdat al-adyan seperti dijelaskan dalam dua bukunya; Futuhat dan Fusus, dan perbedaan dan kesamaan antara iman dan shariah.

Dalam diskusinya, Ibn Arabi’  menjelaskan perbedaan ‘ideal’ dan ‘historikal’ atau antara ‘esoterik’ dan ‘eksoterik’. Ibn ‘Arabi berpendapat bahwa kemanunggalan agama-agama dapat dicapai melalui spiritualitas, ideal, atau dimensi transcendental (esoterik yang ada di luar tampilan formal agama-agama.

By overcoming the supposed division between law and morality, considering the interpretive activity the central element of a normative theory of all human endeavor, Dworkin highlights the limitations of legal positivism designed by Hart to provide adequate solutions to the "hard cases" and broadens the spectrum to find a "correct answer" to specific cases in a normative theory linked to political morality, expressed by the interpretive activity, whose meaning will be the value assigned by the interpreter to a particular event or object.

    Utilizing Bourdieu's concept of the habitus, Keith Macdonald has recently examined the elite social origins of the British officer corps. His analysis is valid as far at it goes but it ignores the professional practices of British officers. This article examines Britain's Joint Services Command and Staff College to assess the unification of the three services around common forms of military practice. It argues that while the new staff college has been effective in disseminating new forms of professional expertise among British officers, various practices have been institutionalized which actively undermine the unity of the officer corps.

    The explicit construction of irreducible representations of the Hecke algebra H n (q) of type A n-1 was studied for the non-generic case where q is a root of unity. The approach is via the Specht modules of H n (q) which are irreducible in the generic case and possess a natural basis indexed by Young tableaux. The general framework in which the non-generic H n (q)-modules are to be constructed is set up and, in particular, the full set of modules corresponding to two-part partitions is described. Many examples are given. 12 refs

  16. THE ANTIQUE FOUNDATIONS FOR THE UNITY OF EDUCATION

    Directory of Open Access Journals (Sweden)

    Alexander E Krikunov

    2017-12-01

    Full Text Available The author of the paper considers the unity of education as a specific way of existence, blurring the distinction between ontological and anthropological interpretations of education. This approach is supposed to adequately identify the philosophic sense of the category of education without linking it exclusively to the philosophic consideration of educational practice. The author also points out the connection between the ideas of the world unity and of a human being’s education as a process of gradual approaching one’s true and complete image in the history of European philosophy. Even though the contemporary notion of education is most elaborately presented by classical German philosophers, the author aims to show the prospects of addressing the antique philosophic tradition proposing the first conceptualization of education connected with a special ontological position. The author calls attention to the gradual development of views on the systemic nature of being, linking it to the initial didactic guideline of Greek philosophers. The example of Aristotle’s ethics proves the integrity of externally separate ways of making up of a person. The author comes to a conclusion about the necessity of taking the connection of educational concepts and a characteristic tendency to create the philosophic theory of the world, the elements of which are united in an integrated system, into account. In the author’s opinion, it will allow to define the real philosophic and pedagogical sense of the revision of the classical philosophic tradition, undertaken by the contemporary philosophy.

    Full Text Available The proposed unity power factor converter system which is able to operate from a 150V three-phase supply whilst delivering the required 200V DC voltage has been built and tested. This circuit functions as a high power factor low harmonic rectifier based on the concept that the peak capacitor voltages are proportional to the line input currents. Hence the low frequency components of the capacitor voltages are also approximately proportional to the line input currents. The system can be designed to achieve nearly sinusoidal supply input currents, when operated with discontinuous resonant capacitor voltages Output power control is achieved by variations of the IGBTs switching frequency. The converter is therefore able to compensate for any changes in the load resistance. The proposed topology offers advantages, including: a relatively simple power, control and protection circuits, high power capability, and high converter efficiencies.

    Full Text Available This paper represents the outcome of research fellowship Marie Curie at the Universiteit Leiden -Campud Den Haag Grotius, Centre for International Legal Studies (prof. C. Stahn and prof. Larissa van den Herik, supervisors on the topic "The Fragmentation and the Diversification of International Criminal Law in a Global Society”.In my paper I will examine the question of whether Universal Jurisdiction (UJ leads to unity or fragmentation within International Criminal Law (ICL. Given that there is already quite a lot of literature on UJ, it is important to focus the research on the issue of fragmentation and/or unity rather than to deal with the issue of UJ more generally. I will focus on this topic in sections 1 and 2, explaining some cursory remarks to these issues in my analysis on fragmentation. In the introduction, I will briefly introduce UJ as a controversial form of jurisdiction, but still necessary given that territorial jurisdiction does not always function well in the case of international crime. I will demonstrate that many state parties to the International Criminal Court (ICC Statute have vested or reconfirmed UJ for the core crimes when implementing the ICC Statute. The leading question of my research is whether this practice has led or has the potential to lead to unity or rather to fragmentation within ICL. In the research I will approach this question from different perspectives.In section 1 I will examine how State parties have may actually enacted universal jurisdiction for the core crimes, with a view to determining whether there is indeed some unity on this front or whether the practice on this matter is actually rather diverse (or fragmented. Subsequently, I will analyse which conditions States have formulated for the exercise of UJ, and whether this practice is consistent (unity or again rather diverse (fragmentation. It might also be interesting to see whether States have different conditions for UJ over core crimes than

  7. Controlling coulomb interactions in infrared stereometamaterials for unity light absorption

    2018-05-01

    We investigate the influence of near field interactions between the constituent 3D split ring resonators on the absorbance and resonance frequency of a stereo metamaterial based perfect light absorber. The experimental and theoretical analyses reveal that the magnetic resonance red shifts and broadens for both the decreasing vertical and lateral separations of the constituents within the metamaterial lattice, analogous to plasmon hybridization. The strong interparticle interactions for higher density reduce the effective cross-section per resonator, which results in weak light absorption observed in both experimental and theoretical analyses. The red shift of the magnetic resonance with increasing lattice density is an indication of the dominating electric dipole interactions and we analyzed the metamaterial system in an electrostatic point of view to explain the observed resonance shift and decreasing absorption peak. From these analyses, we found that the fill factor introduces two competing factors determining the absorption efficiency such as coulomb interactions between the constituent resonators and their number density in a given array structure. We predicted unity light absorption for a fill factor of 0.17 balancing these two opposing factors and demonstrate an experimental absorbance of 99.5% at resonance with our 3D device realized using residual stress induced bending of 2D patterns.

  8. The Paradigm of Unity in Prenatal Education and Pedagogy

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available The traditional approach to the relation between parents and their prenatal child presents the child as a fetus, a mainly passive recipient of the mother’s vital biological resources. Contemporary prenatal psychology and pedagogy recognizes this relationship in a quite different perspective: the prenatal child is a member of the family and may be seen as an active member of the wider family as a community, extended to grandparents and other relatives. Between parents and their child in the womb exists a reciprocal relationship at a physiological (hormonal, psychological and spiritual level. The prenatal child communicates with the parents in different ways and reacts to their stimulation (acoustic, tactile, loco-motoric, chemo-receptive, thermo-receptive, and emotional. This dialogue of the parents and their prenatal child enriches each member of the family community. In this sense, the prenatal child is a gift and a challenge for the parents to develop their personality, social competences and spiritual life. The reflections presented in this paper fit the conception of the paradigm of unity applied into the area of prenatal education and prenatal pedagogy as a new pedagogical subdisciline.

    2016-06-01

    Full Text Available It is undeniable that the European Union represents the most ambitious legal and linguistic project, integrating 28 Member States and 24 official languages. What we undertook with this study was to explore the importance of multilingualism in the European Union and the problems that unity in diversity involves. This study tried to touch upon both theoretical aspects (i.e., what the multilingualism of EU law implies and practical issues (i.e., the interaction between legal languages at national and at EU level, problems emerging from multilingualism, illustrated by the relevant case law of the European Court of Justice. In many ECJ cases, it was underlined that multilingualism is essential to the EU legal order. The meaning of EU law cannot be derived from one version of the official languages and the ECJ regularly heads for a uniform interpretation of the contradictory versions. The present study is part of a more complex research on this theme and it is meant to approach certain important points of my PhD thesis. A first part of this research on multilingualism has already been published.

    The falsifiability of scientific knowledge is an acquired result of contemporary philosophy of science and yet there is not a universal consensus upon the idea of the unity of scientific method. Albeit there are differences in techniques of testing (methodics) hypotheses in the vast field of research, the author, following the critical rationalism of Karl Popper, favors the perspective of the unity of method in natural as well in social and philological sciences.

  15. Unity and catholicity in the Korean Presbyterian Church: An ecumenical Reformed assessment

    Directory of Open Access Journals (Sweden)

    Jaegeon Ha

    2016-03-01

    Full Text Available I attempt to find the main causes of the serious disunity in the Presbyterian Church in Korea (PCK, which started as one church but is now divided into more than 100 denominations, as well as a solution to promote the unity of the PCK. This attempt starts with an exegesis of Ephesians, with special reference to Ephesians 4:1�16, to understand the biblical principle on this matter. This article draws on a mature ecclesiology and a mature sense of unity as key concepts. After that, the history of the PCK disunity is briefly described, dealing with four major schisms. Based on this historical investigation, the disunity in the PCK is assessed. In addition, the weak sense of unity and weak ecclesiology of the PCK, which played a role in its disunity, are discussed in view of the confessions of faith, the ministry of the word and the Lord�s Supper, and ecumenical efforts in relation to national and international ecumenical organisations. Lastly, contributory suggestions based on the mature sense of unity are offered to the PCK in particular and the Reformed family and all Christian churches in general.Intradisciplinary and/or interdisciplinary implications: In my ecumenical Reformed intradisciplinary assessment of unity and catholicity in the PCK, which started as one church but is now divided into more than 100 denominations, I identify the main causes of serious disunity in the PCK, namely a weak sense of unity, immaturity and secularisation.

  17. The mystical Unity of Existence: A look at the philosophical interpretations of the mystics' view regarding The Unity vs. The plurality of existence

    Directory of Open Access Journals (Sweden)

    Agha Husain Shiraz

    2017-01-01

    Full Text Available The Unity of Existence is a concept that was first proposed by mystics. However, this concept has been interpreted in different ways by different groups of scholars. This is due to the fact that these mystics did not always speak in an explicit manner. One of the groups that attempted to interpret this concept was the philosophers. An examination of the works of philosophers leads to the conclusion that there are at least 15 different philosophical interpretations of the Unity of Existence. Some of these interpret this concept epistemologically, while others interpret it metaphysically. Some of them are legitimate interpretations of the sayings of the mystics, while others contradict some of the other sayings of the mystics and, therefore, cannot serve as adequate explanations of this mystical concept. Nonetheless, they can still serve as independent interpretations of the unity vs. multiplicity of the Universe. In this article, the 15 different philosophical interpretations of the mystical unity of existence will be presented and the legitimacy of some of them will be assessed. Another discussion that is of primary importance is the truth or falsehood of these interpretations. This is something that cannot be addressed in this article and, yet, deserves to be examined independently.

  18. Disease prevalence and the index of detectability: a survey of studies of lung cancer detection by chest radiography

    Kundel, Harold L.

    2000-04-01

    A survey of 12 studies of lung cancer detection with cancer prevalence ranging from 0.9 to 476 cancers per 1000 showed that the unit-slope index of detectability, d', decreased from a high value of 3.9 at low prevalence to 1.4 at high prevalence. A proposed explanation is that the readers are operating on an ROC curve with a slope that is less than unity approximating 0.6. On such a curve, a shift to more stringent criteria that occurs with decreasing prevalence in order to minimize false positives, would result in a increased unity- slope d'.

  19. The diversity and unity of reactor noise theory

    International Nuclear Information System (INIS)

    Kuang, Zhifeng

    2001-01-01

    The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. The neutron noise in zero-energy systems arises from the fluctuations in the number of neutrons per fission, the time between nuclear events, and the type of reactions. It can be used to evaluate system parameters. The mathematical treatment is based on the master equation of stochastic branching processes. The noise in power reactor systems is given rise by random processes of technological origin such as vibration of mechanical parts, boiling of the coolant, fluctuations of temperature and pressure. It can be used to monitor the reactor behaviour with the possibility of detecting malfunctions at an early stage. The mathematical treatment is based on the Langevin equation. The unity of reactor noise theory arises from the fact that the useful information from noise is embedded in the second moments of random variables, which lends the possibility of building up a unified mathematical description and analysis of the various reactor noise sources. Exploring such possibilities is the main subject among the three major topics reported in this thesis. The first subject is within the zero power noise in steady media, and we reported on the extension of the existing theory to more general cases. In Paper I, by use of the master equation approach, we have derived the most general Feynman- and Rossi-alpha formulae so far by taking the full joint statistics of the prompt and all the six groups of delayed neutron precursors, and a multiple emission source into account. The involved problems are solved with a combination of effective analytical techniques and symbolic algebra codes. Paper II gives a numerical evaluation of these formulae. An assessment of the

    Using the cross-platform game engine Unity, we develop virtual laboratories for PC, consoles, mobile devices and website as an innovative tool to study physics. There is extensive uptake of ICT in the teaching of science and its impact on the learning, and considering the limited availability of laboratories for physics teaching and the difficulties this causes in the learning of school students, we design the virtual laboratories to enhance studentâĂŹs knowledge of concepts in physics. To achieve this goal, we use Unity due to provide support bump mapping, reflection mapping, parallax mapping, dynamics shadows using shadows maps, full-screen post-processing effects and render-to-texture. Unity can use the best variant for the current video hardware and, if none are compatible, to use an alternative shader that may sacrifice features for performance. The control over delivery to mobile devices, web browsers, consoles and desktops is the main reason Unity is the best option among the same kind cross-platform. Supported platforms include Android, Apple TV, Linux, iOS, Nintendo 3DS line, macOS, PlayStation 4, Windows Phone 8, Wii but also an asset server and Nvidia’s PhysX physics engine which is the most relevant tool on Unity for our PhysLab.

  1. Organic unity theory: an integrative mind-body theory for psychiatry.

    Science.gov (United States)

    Goodman, A

    1997-12-01

    The potential of psychiatry as an integrative science has been impeded by an internal schism that derives from the duality of mental and physical. Organic unity theory is proposed as a conceptual framework that brings together the terms of the mind-body duality in one coherent perspective. Organic unity theory is braided of three strands: identity, which describes the relationship between mentally described events and corresponding physically described events; continuity, which describes the linguistic-conceptual system that contains both mental and physical terms; and dialectic, which describes the relationship between the empirical way of knowing that is associated with the physical domain of the linguistic-conceptual system and the hermeneutic way of knowing that is associated with the mental domain. Each strand represents an integrative formulation that resolves an aspect of mental-physical dualism into an underlying unity. After the theory is presented, its implications for psychiatry are briefly considered.

  2. Does John 17:11b, 21−23 refer to church unity?

    Directory of Open Access Journals (Sweden)

    Gert J. Malan

    2011-04-01

    Full Text Available In ecumenical circles, John 17:11b, 21–23 has been understood as Jesus’ prayer for church unity, be it confessional or structural. This article questioned such readings and conclusions from historical, literary and sosio-cultural viewpoints. The Fourth Gospel’s language is identified as ’antilanguage’ typical of an ’antisociety’, like that of the Hermetic, Mandean and Qumran sects. Such a society is a separate entity within society at large, but opposes it. Read as a text of an antisociety, John 17:11b, 21–23 legitimises the unity of the separatist Johannine community, which could have comprised several such communities. This community opposed the Judean religion, Gnosticism, the followers of John the Baptist and three major groups in early Christianity. As text from the canon, this Johannine text legitimates tolerance of diversity rather than the confessional or structural unity of the church.

    2011-01-01

    Feeling that you belong in a group is an important and powerful need. The ability to foster a sense of belonging can also determine whether groups survive. Organizational features of groups cultivate feelings of belonging, yet prior research fails to investigate the idea that belief systems also play a major role. Using multilevel data, this study finds that church members' traditional beliefs, group-level belief unity, and their interaction associate positively with members' sense of belonging. In fact, belief unity can be thought of as a “sacred canopy” under which the relationship between traditional beliefs and feelings of belonging thrives.

    Directory of Open Access Journals (Sweden)

    Maryamsaday Eizadi

    2013-12-01

    Full Text Available Tawhid (the belief in transcendent oneness or unity of divinity is the culmination of all Islamic teachings and has a special place in Islamic sciences. The unity of essence begins by the unity of existential necessity and ends in unity of existence as many theosophers and mystics suggest. This essay discusses unity of essence as understood by two Sadraean thinkers (Hakim Mudarres Zunuzi and Banu Amin according to Mulla Sadra's principles. Undoubtedly, these two theosophers have no discord as far as they speak about necessity of existence and unity of Necessary Existence. Dispute erupts when Banu voices her Sadraean sympathy with transcendent oneness of existence while Mudarres takes another position.       According to Sadra, the being which has no limitation whatsoever leaves no room for other being to come into existence and be its second or third and thus it is unique and uncountable. In this world, thus, there is no existence but one of which the rest are manifestations (Mulla Sadra, 1382, 67. This view which has been mentioned by Sadra in different positions is the very idea of individual unity of existence. It needs to be explained that in Mulla Sadra's works there are two accounts of effect: Existence in itself for something-else (relational existence Existence for something-else (copulative existence      At first sight which is thought to be elementary as compared to the second one, effect enjoys a reality and existence of its own the whole identity of which is though being related to and depended on cause and this dependency is its very essence and undetachable but the effect like the cause is counted among  beings. This is the position which is also held by Mudarres Zunuzi as to contingent beings (Mudarres Zunuzi, 1376: 357. He seem to have understood Mulla Sadra's words implying this very sense alone without presuming the possibility of a second sense. To put it otherwise, he has indeed fathomed effect's copulative

The two mentioned categories: meeting and paradigm of unity are not presented in the literature in the context of their direct relation to each other. Therefore, the main problem presented in the paper is: how far they are cognitively relevant. The starting point for reflections is the recognition of a meeting situation in the perspective of human spiritual development which happens through turning towards the other. This development is experienced in overcoming the tension between the declarative attitude towards the mutual love and the real act expressing the actual openness to this gift. According to Chiara Lubich, the gift of love is the central category of the paradigm of unity. If we follow Thomas Kuhn and define the paradigm as a worldview that unites a community in their holistic vision of the world, then it is the meeting that is an integral and necessary element of this paradigm. Experiencing a meeting, in this context, is the condition for reaching the spiritual unity in a community of people who are led by mutual love and out of that love bear with one another in their otherness.

    Full Text Available The purpose of this paper is to show the methodological power and potentiality of the concept paradigm of unity introduced originally in the ceremony on the occasion of honoring Chiara Lubich with the doctor honoris causa title by the Catholic University of Lublin in 1996. Originally this conception was used to suggest the societal activity of Chiara Lubich in building, via the Focolari movement, psychosocial infrastructures for unity in various social domains, (for example in the economy of communion, in politics (politicians for unity project, in public media (journalists for unity, in ecumenism and inter-religious contacts (ecumenical and inter-religion Focolari Centers This conception is a kind of a great inspiration (a kind of Copernican revolution in the social sciences which would motivate the social sciences to build their own research paradigm of a type of mental and methodological power and potentiality which could give a new vision of social world (as Copernicus did in natural sciences (Biela, 1996, 2006. Thomas Kuhn (1962 regarded the Copernician revolution as the one which, in the history of science, best illustrates the nature of scientific revolution. The essence of paradigm in a Kuhnian sense is a mentality change in its nature. Copernicus had to change the well-established geocentric system which functioned not only in the science of his day but also in culture, tradition, social perception, and even in the mentality of religious and political authorities. And he did it in a well prepared empirical, methodological and psychological way.

    2000-05-01

    A family of organically templated aluminophosphates (denoted AlPOs) with an Al/P ratio of non-unity has been prepared with 1-D chain, 2-D layer and 3-D open-framework architectures. Their inorganic parts are constructed from alternating Al-centered polyhedra (AlO 4, AlO 5, AlO 4(OH 2) 2) and P-centered tetrahedra P(OAl) nO 4- n ( n=0, 1, 2, 3). The existence of terminal POH and/or PO groups in the structures results in the deviation of Al/P ratio from unity, and the commonly encountered Al/P ratios are 1/2, 3/5, 2/3, 3/4, 4/5 and 5/6. This review will discuss the structural features of these AlPOs with various dimensionalities and stoichiometries.

  5. The one and the many: the search for unity in nature.

    Science.gov (United States)

    Gleiser, Marcelo

    2015-12-01

    The essence of physical reality-what the world consists of-has been a heated focus of contention for millennia. First with philosophers and then with physicists, the debate has been polarized since the beginning: while those loosely known as Platonists search for an underlying unity in nature, others caution that such unity is unachievable in practice and in principle. In this essay, we review both positions, arguing strongly for the latter in anticipation of experimental results from the Large Hadron Collider, the particle accelerator from the European Center for Nuclear Research. We further argue that, for the first time in history, the material essence of reality could be determined from an empirical standpoint as opposed to a purely dialectic one, settling the age-old debate. © 2015 New York Academy of Sciences.

    Quantum groups in general and the quantum Anti-de Sitter group U q (so(2,3)) in particular are studied from the point of view of quantum field theory. The author shows that if q is a suitable root of unity, there exist finite-dimensional, unitary representations corresponding to essentially all the classical one-particle representations with (half) integer spin, with the same structure at low energies as in the classical case. In the massless case for spin ≥ 1, open-quotes naiveclose quotes representations are unitarizable only after factoring out a subspace of open-quotes pure gaugesclose quotes, as classically. Unitary many-particle representations are defined, with the correct classical limit. Furthermore, the author identifies a remarkable element Q in the center of U q (g), which plays the role of a BRST operator in the case of U q (so(2,3)) at roots of unity, for any spin ≥ 1. The associated ghosts are an intrinsic part of the indecomposable representations. The author shows how to define an involution on algebras of creation and anihilation operators at roots of unity, in an example corresponding to non-identical particles. It is shown how nonabelian gauge fields appear naturally in this framework, without having to define connections on fiber bundles. Integration on Quantum Euclidean space and sphere and on Anti-de Sitter space is studied as well. The author gives a conjecture how Q can be used in general to analyze the structure of indecomposable representations, and to define a new, completely reducible associative (tensor) product of representations at roots of unity, which generalizes the standard open-quotes truncatedclose quotes tensor product as well as many-particle representations

  9. Body-self unity and self-esteem in patients with rheumatic diseases.

    Perceptions and evaluations of the own body are important sources of self-esteem. Having a rheumatic disease challenges maintenance of positive self-esteem due to consequences of the disease such as unfavorable sensations as pain and limited (physical) functioning. We expect that a positive experience of the own body in spite of a rheumatic disease (body-self harmony) will be associated with higher levels of self-esteem and that experiencing the body as unworthy part of the own person or as disabler for own strivings (body-self alienation) will result in lower levels of self-esteem. For this explorative study, the body experience questionnaire (BEQ) measuring body-self unity was developed and piloted. One hundred sixty-eight patients visiting the outpatient rheumatology clinic of the Medisch Spectrum Twente, Enschede, The Netherlands, completed a questionnaire on touchscreen computers to measure body-self unity (BEQ), illness cognitions (illness cognition questionnaire), pain intensity, functional limitations (health assessment questionnaire disability index), self-esteem (Rosenberg Self-Esteem Scale) and demographics. To analyze predictors of self-esteem, hierarchical regression analyses were employed. The BEQ revealed a two-factor structure with good reliability (subscale harmony, four items, Cronbach's α = 0.76; subscale alienation, six items, Cronbach's α = 0.84). The final model of the hierarchical regression analyses showed that self-esteem can be predicted by the illness cognitions helplessness and acceptance, by harmony and most strongly by alienation from the body. R(2) of the final model was 0.50. The relationship between functional limitations and self-esteem was totally mediated by the psychological constructs body-self unity and illness cognitions. This explorative study showed the importance of the unity of body and self for self-esteem in patients with a rheumatic disease.

It is argued that the events surrounding Christ constituted for John the central point of orientation according to which the typical Jewish ideas could be interpreted and reformulated. It is finally concluded that, according to this radical and exclusive Christian dynamic approach, certain elements within Judaism, also found among members of the Qumran community, were reinterpreted, while others were either continued or discontinued.

  4. Geomicrobiology; inseparable from low temperature geochemistry & mineralogy

    Science.gov (United States)

    Southam, G.

    2009-05-01

    Bacteria play an important role in catalyzing a wide array of biogeochemical processes that affect the dissolution of minerals, the aqueous geochemistry of their surroundings and secondary mineral formation. Processes occurring at the bacteria-mineral interface can occur on the scale of nanoenvironments and will normally extend to microenvironments or even, to macroscopic features where extensive growth of bacteria is supported. The action of bacteria in these systems can produce a wide range of biomarkers that can be preserved over geologic time periods. Possible biomarkers include dissolution features in mineral substrates, fossil structures of individual cells to complex cell-cell associations, and chemical (isotopic and organic) signatures. In any system, we need to focus at the scale of the bacteria themselves to appreciate the actual chemistry of their surroundings and the kinds of reactions that they can catalyse. For example, photosynthetic microbial mats in an Atlin, BC wetland create ideal conditions for biologically induced precipitation of magnesium carbonates, specifically dypingite Mg5(CO3)4(OH)25H2O, which we were unable to reproduce abiotically. The preservation of biosignatures over geologic time presents obvious challenges, and the effect of diagenesis on fossils and their mineralogical assemblages deserves attention, especially with respect to the preservation and analysis of materials on (or from) Mars. For this, we need to rely on our Earth analogue sites as a way to triage the wide range of samples that are available for collection and analysis. The preservation of organic materials and cells in salts is particularly interesting. Conversely, the hematite nodules on Mars may not be good samples to target in the search for a Martian biosphere. The possibility of finding an extant biosphere increases with depth; however, evidence from Earth's deep subsurface demonstrates that it does not contain an abundant biosphere. Bacteria thrive in geochemical gradients where they take advantage of disequilibrium conditions to generate the energy needed to fight entropy. The selection of analogue sites needs to focus on the habitable conditions and preservation potential of these sites in order to increase our chances of finding evidence of life, to better understand how it is preserved on Earth, and by extension, to determine where it might be preserved on Mars.

On the other hand, it leads to a new state-independent proof of the Kochen-Specker theorem and provides a wider perspective on the relations between the major proofs of no hidden variables

    When the input-output mapping of a one-layered perceptron (OLP) does NOT meet the PLI condition which is the if-and- only-if, or 'IFF, condition that the mapping can be realized by a OLP, then no matter what learning rule we use, a OLP just cannot realize this mapping at all. However, because of the nature of the PLI, one can still construct a parallel- cascaded, two-layered perceptron system to realize this `illegal' mapping. Theory and design example of this novel design will be reported in detail in this paper.

Islam is often perceived as a harsh, exclusive and sectarian religion, whereas Islam is full of moral values, compassion, tolerance and inclusion. In response, Islamic education is required to give an understanding to the world that Islam is a religion that respects multiculturalism. This is where Islamic education with multicultural insight must be present in order to explain the relationship between man and God (hablun min Allah, theological aspects; the relationship of unity, namely human relationships with others (hablun min al-nas, anthropo-sociological aspects; and human relationship with the natural surroundings (hablun mi al-’Alam, cosmological aspect.

    Full Text Available Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

    A model for monitoring catalyst mass flow in riser of Fluid Catalytic Cracking - FCC, pilot unity as a function of air flow and solid injection is proposed. The fluidized FCC- catalyst bed system is investigated in an experimental setup the Cold Pilot Unity - CPU by means of gamma ray transmission measurements. Riser in CPU simulates the reactor in FCC process. By automation control air flow is instrumentally measured in riser and the solid injection is manually controlled by valve adjusting. Keeping a constant solid injection, catalyst level at the return column was measured by gamma transmission for several air flow values in riser. The operational condition reached a steady state regime before given to setup a new air flow value. A calibration of catalyst level as a function of air flow in riser is calculated, therefore, a model for solid feed rate is derived. Recent published work evaluates solid concentration in riser of the CPU by means of gamma ray transmission, and a correlation with air velocity is obtained. In this work, the model for solid feed rate was further investigated by carrying out experiments to measure catalyst concentration at the same air flow values. These experiments lead to a model for monitoring catalyst flow in riser as function of solid feed rate and air flow. Simulation with random numbers produced with Matlab software allows to define validation criteria for the model parameters. (author)

  13. The concept of society’s organic unity and its representation in the historiosophy of Vladimir Soloviev and the early Slavophiles

    Full Text Available The meaning of the concept of society’s organic unity has been investigated. This concept was an important part of Russian religious philosophy in the middle of the XIX century. It has been found that Schelling and Hegel idealistic philosophy and orthodox theology were the main sources of the concept of organic unity. The character and forms of the presentation of the organic unity’s concept in Vladimir Soloviev and the main representatives of early Slavophilism’s social philosophy and philosophy of history has been analyzed. By Solovyov, the subject of the historical development is mankind as holistic, organic phenomenon which tries to overcome the formal unity and to reach its spiritual level in the form of «God-manhood». Economic and legal unity is called the lowest form of unity by Solovyov, and the highest one, which reaches the organic and conscious level, is the spiritual unity. In the philosophy of Ivan Kireyevski, society’s organic unity is opposed to the formal, rational unity. The formal unity was inherited by Europe from ancient Rome. Cultural traditions of Greece and Orthodoxy were inherited by Slavs and saved the spiritual unity of society. According to Alexey Khomyakov, there are two contrasting models of culture: Iranian and Cushitic ones. Iranian model is based on freedom and conscious action. Iranian model creates a spiritual unity without suppression of individuals in society. Cushitic model creates a formal unity, it coercions and suppress individuals. The formality of the state association and the spiritual unity of the community have been opposed by Konstantin Aksakov. In tsarist Russia, all power was given to the monarch to protect the community. Therefore, Russia maintained an organic, internal unity of the people unlike Europe. In Europe, the state became stronger then the communities and state there suppressed communities. Rights and economy became to be more important than morality. European society became

    Nonfullerene solar cells have increased their efficiencies up to 13%, yet quantum efficiencies are still limited to 80%. Here we report efficient nonfullerene solar cells with quantum efficiencies approaching unity. This is achieved with overlapping absorption bands of donor and acceptor that increases the photon absorption strength in the range from about 570 to 700 nm, thus, almost all incident photons are absorbed in the active layer. The charges generated are found to dissociate with negligible geminate recombination losses resulting in a short-circuit current density of 20 mA cm -2 along with open-circuit voltages >1 V, which is remarkable for a 1.6 eV bandgap system. Most importantly, the unique nano-morphology of the donor:acceptor blend results in a substantially improved stability under illumination. Understanding the efficient charge separation in nonfullerene acceptors can pave the way to robust and recombination-free organic solar cells.

    Full Text Available For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA formalism of Sklyanin. However, when q is a root of unity (q=eiπ/p with integer p≥2, the Bethe equations acquire continuous solutions, and the transfer matrix develops Jordan cells. Hence, there appear eigenvectors of two new types: eigenvectors corresponding to continuous solutions (exact complete p-strings, and generalized eigenvectors. We propose general ABA constructions for these two new types of eigenvectors. We present many explicit examples, and we construct complete sets of (generalized eigenvectors for various values of p and N.

    Full Text Available This text explores some of the great challenges present in the cultural landscape of today, such as globalization and its associated phenomena – (internationalisation and ultra-contemporaneousness; exasperated economism with its outcome in the scrap culture; the “piecemeal third world war”, according to Pope Francis’ effective expression, which is connected with a widespread and still poorly understood post-humanism and transhumanism; nihilism and the eclipse of religion as an institution. It considers the light that might be shed by the culture arising from the Focolare’s charism of unity, in order to address these challenges rigorously and without hasty demonizing. The overall picture is not intended to be negative but, without being naive, to offer an interpretation that is able to discern the work of the Spirit in the dramatic scenario of present times.

    Intrinsic gain (AV) measurements on Si quantum well (QW) n-channel metal-oxide-semiconductor (NMOS) transistors show that these devices can have |AV| > 1 in quantum transport negative transconductance (NTC) operation at room temperature. QW NMOS devices were fabricated using an industrial 45 nm technology node process incorporating ion implanted potential barriers to define a lateral QW in the conduction channel under the gate. While NTC at room temperature arising from transport through gate-controlled QW bound states has been previously established, it was unknown whether the quantum NTC mechanism could support gain magnitude exceeding unity. Bias conditions were found giving both positive and negative AV with |AV| > 1 at room temperature. This result means that QW NMOS devices could be useful in amplifier and oscillator applications.

    Zames (1981) has observed that there is, in general, no 'separation principle' to guarantee optimality of a division between control law design and filtering of plant uncertainty. Peczkowski and Sain (1978) have solved a model matching problem using transfer functions. Taking into consideration this investigation, Peczkowski et al. (1979) proposed the Total Synthesis Problem (TSP), wherein both the command/output-response and command/control-response are to be synthesized, subject to the plant constraint. The TSP concept can be subdivided into a Nominal Design Problem (NDP), which is not dependent upon specific controller structures, and a Feedback Synthesis Problem (FSP), which is. Gejji (1980) found that NDP was characterized in terms of the plant structural matrices and a single, 'good' transfer function matrix. Sain et al. (1981) have extended this NDP work. The present investigation is concerned with a study of FSP for the unity feedback case. NDP, together with feedback synthesis, is understood as a Total Synthesis Problem.

    Refractive index and scattering can significantly influence the transfer of radiation in a semitransparent medium such as water, glass, plastics, or ceramics. In a recent article (1979), the author presented exact numerical results for the emittance of a semiinfinite scattering medium with a refractive index greater than unity. The present investigation extends the analysis to a finite medium. The physical situation consists of a finite planar layer. The isothermal layer emits, absorbs, and isotropically scatters thermal radiation. It is characterized by single scattering albedo, optical thickness, refractive index, and temperature. A formula for the directional emittance is derived, the directional emittance being the emittance of the medium multiplied by the interface transmittance. The ratio of hemispherical to normal emittance is tabulated and discussed

    In this paper, we present a linear polarization converter in the reflective mode with near unity conversion efficiency. The converter is designed in an array form on the basis of a pair of orthogonally arranged three-dimensional split-loop resonators sharing a common terminal coaxial port and a continuous metallic ground slab. It converts the linearly polarized incident electromagnetic wave at resonance to its orthogonal counterpart upon the reflection mode. The conversion mechanism is explained by an equivalent circuit model, and the conversion efficiency can be tuned by changing the impedance of the terminal port. Such a scheme of the linear polarization converter has potential applications in microwave communications, remote sensing, and imaging.

    The "Unity of Knowing and Doing" (UKD) theory is proposed by an ancient Chinese philosopher, Wang Shouren, in 1508, which explains how to unify knowledge and practice. Different from the Chinese traditional UKD theory, the international higher education usually treats knowledge and practice as independent, and puts more emphasis on knowledge. Oriented from the UKD theory, the College of Opto-electric Science and Engineering (COESE) at National University of Defense Technology (NUDT) explores a novel training model in cultivating opto-electric professionals from the aspects of classroom teaching, practice experiment, system experiment, design experiment, research experiment and innovation experiment (CPSDRI). This model aims at promoting the unity of knowledge and practice, takes how to improve the students' capability as the main concern and tries to enhance the progress from cognition to professional action competence. It contains two hierarchies: cognition (CPS) and action competence (DRI). In the cognition hierarchy, students will focus on learning and mastering the professional knowledge of optics, opto-electric technology, laser, computer, electronics and machine through classroom teaching, practice experiment and system experiment (CPS). Great attention will be paid to case teaching, which links knowledge with practice. In the action competence hierarchy, emphasis will be placed on promoting students' capability of using knowledge to solve practical problems through design experiment, research experiment and innovation experiment (DRI). In this model, knowledge is divided into different modules and capability is cultivated on different levels. It combines classroom teaching and experimental teaching in a synergetic way and unifies cognition and practice, which is a valuable reference to the opto-electric undergraduate professionals' cultivation.

    To generate a substantive grounded theory of relatives' pattern of behaviour in older patients' fast-track treatment programmes during total hip or knee replacement. Fast-track treatment programmes are designed to make total hip and knee replacements more efficient through recovery improvements. The support of relatives during older patients' trajectory is important. However, knowledge is needed on the relatives' pattern of behaviour to strengthen their involvement in fast-track treatment programmes. We used a Glaserian grounded theory approach based on a systematic generation of theory from data to explain the latent pattern of behaviour of relatives. Data were collected from 2010-2011 in orthopaedic wards at two Danish university hospitals and consisted of 14 non-participant observations, 14 postobservational interviews and five interviews. Seven relatives of patients over 70 years of age participated. The constant comparative method was the guiding principle for simultaneous data collection, data analysis and coding, while theoretically sampling and writing memos. Maintaining Unity emerged as the relatives' pattern of behaviour through which they resolved their main concern: preventing the patients from feeling alone. The relatives resolved their main concern through three interchangeable behavioural modes: Protecting Mode, by providing loving and respectful support; Substituting Mode, with practical and cognitive support; and an Adapting Mode, by trying to fit in with the patients' and health professionals' requirements. The substantive theory of Maintaining Unity offers knowledge of relatives' strong desire to provide compassionate and loving support for the older patients during fast-track treatment programmes. © 2014 John Wiley & Sons Ltd.

    Full Text Available The article examines the phenomenon of corporatism, which under the adverse external environment can be used by the professional community to improve the effectiveness of organization. The authors define corporatism of the professional society as a combination of homogenous interests, attitudes, traditions and values; and provide a sociological interpretation of the corporate unity through its organizational and behavioral parameters. The former consists of the perception of the organization reliability, the staff’s confidence in the future, satisfaction with the financial situation (static features, estimates of the innovative capabilities of the company, and the willingness to develop (dynamic features. The behavioral parameters include staff’s values and patterns of behavior that can contribute to the consolidation of the professional community. The authors believe that for corporate management vertical social ties are less important that the horizontal ones, such as the rule of law and honesty, and the team unity under the unstable external environment. The sample of the study conducted by the authors in 2015 consisted of various types of settlements typical for the Sverdlovsk Region: mono-towns and mono-settlements (Nizhny Tagil, Serov, towns and villages with the differentiated economic activities (Ekaterinburg, Irbit. The results of the empirical study of corporatism among different professional societies - industrial workers, social services’ and business organizations’ staff, individual entrepreneurs and authorities - revealed the internal resources that can reduce tensions on the labor market. The research data can be useful for the comparative analysis of corporatism in different regions of Russia (not only industrial and similar to the Ural Region, but differing from it by significant social and economic parameters.

  10. Sustainability Science as a Transdisciplinary Framework for Institutional Transformation at Unity College

    Science.gov (United States)

    Mulkey, S. S.

    2012-12-01

    Interdisciplinary programming in higher education is accepted as necessary for effective instructional delivery of complex environmental problems. Difficulties in sharing resources among disciplinary units and the need for students to sequentially access information from different disciplines limit the effectiveness of this approach. In contrast, transdisciplinary programming requires that the perspectives of various disciplines be simultaneously integrated in problem-focused pedagogy. Unity College, an environmental college in Maine, has recently adopted Sustainability Science (sensu U.S. National Academy of Science) as a framework for transdisciplinary pedagogy throughout all of its degree programs. Sustainability Science is a promising alternative framework that focuses on the dynamics of coupled human-natural systems and is defined by the problems that it addresses rather than by the disciplines it employs. Students are empowered to become brokers of knowledge, while faculty perform a curatorial role to provide students with networked resources generally external to the classroom. Although the transdisciplinary framework is effective for delivery of Sustainability Science in upper division and capstone courses, we propose this approach also for elements of our general education curriculum during the first two years of our baccalaureate programs. Classroom time is liberated for experiential student engagement and recitation. Our experience suggests that transdisciplinary programming can provide students with critical thinking skills and thus enhance the postgraduate value of their baccalaureate degree. We are coordinating the development of this distinctive curriculum delivery with a marketing program that will make Unity College accessible to a wider range of clientele. Our implementation of transdisciplinary programming will occur over a four-year period and requires explicit and fundamental change in essentially all aspects of College administration and

    Turbulence statistics from two three-dimensional direct numerical simulations of planar n-heptane/air turbulent jets are compared to assess the effect of the gas-phase species diffusion model on flame dynamics and soot formation. The Reynolds number based on the initial jet width and velocity is around 15, 000, corresponding to a Taylor scale Reynolds number in the range 100 ≤ Reλ ≤ 150. In one simulation, multicomponent transport based on a mixture-averaged approach is employed, while in the other the gas-phase species Lewis numbers are set equal to unity. The statistics of temperature and major species obtained with the mixture-averaged formulation are very similar to those in the unity Lewis number case. In both cases, the statistics of temperature are captured with remarkable accuracy by a laminar flamelet model with unity Lewis numbers. On the contrary, a flamelet with a mixture-averaged diffusion model, which corresponds to the model used in the multi-component diffusion three-dimensional DNS, produces significant differences with respect to the DNS results. The total mass of soot precursors decreases by 20-30% with the unity Lewis number approximation, and their distribution is more homogeneous in space and time. Due to the non-linearity of the soot growth rate with respect to the precursors' concentration, the soot mass yield decreases by a factor of two. Being strongly affected by coagulation, soot number density is not altered significantly if the unity Lewis number model is used rather than the mixture-averaged diffusion. The dominant role of turbulent transport over differential diffusion effects is expected to become more pronounced for higher Reynolds numbers. © 2016 The Combustion Institute.

    2017-04-01

    Rockfall is a geological process that poses risks to the safe operation of transportation infrastructure in mountainous environments world wide. The Unity rockfall model was created as a tool for 3D rockfall simulation as part of the Railway Ground Hazards Research Program, studying the impact of geotechnical hazards affecting Canadian railways [1]. The Unity rockfall model demonstrates the applicability of 3D video game engines for the development of realistic simulations, leveraging high-resolution site data collected using remote sensing techniques. Currently work is being done to further calibrate the model as an engineering tool for decision support. Calibration datasets include high-resolution terrestrial LiDAR and helicopter photogrammetry data collected as part of an ongoing rockfall monitoring program along the Thompson River Valley in south-central British Columbia, Canada. Change detection techniques developed as part of the program have been used to construct a database of rockfall event history and to develop magnitude-frequency relationships for rockfalls in the area [2][3]. Data collected as part of a controlled rock-rolling field program in Christchurch, New Zealand [4] is also being utilized for model calibration. Data on block dynamics for the artificially triggered rockfalls were collected through the use of embedded motion sensors and a sixteen camera setup. These experiments provide detailed information on block kinematics, and capture each impact point of the rockfall with the slope, thus offering a valuable dataset for comparison with modelling results. The research reported here explores the ability of the game engine based modelling technique to simulate rockfall under the variable slope conditions present at each of the sites where calibration data was collected. This includes steep natural rock slopes, with debris-talus cover, as well as shallower slopes with soil cover and vegetation. The varying slope conditions in each environment

    3D City modelling is increasingly popular and becoming valuable tools in managing big cities. Urban and energy planning, landscape, noise-sewage modelling, underground mapping and navigation are among the applications/fields which really depend on 3D modelling for their effectiveness operations. Several research areas and implementation projects had been carried out to provide the most reliable 3D data format for sharing and functionalities as well as visualization platform and analysis. For instance, BIMTAS company has recently completed a project to estimate potential solar energy on 3D buildings for the whole Istanbul and now focussing on 3D utility underground mapping for a pilot case study. The research and implementation standard on 3D City Model domain (3D data sharing and visualization schema) is based on CityGML schema version 2.0. However, there are some limitations and issues in implementation phase for large dataset. Most of the limitations were due to the visualization, database integration and analysis platform (Unity3D game engine) as highlighted in this paper.

    Creation of Unit Theory Oil Generation based on a number of the provisions, one of which is the unity of the hydrocarbon composition in various geological objects. Studies conducted in various geological conditions and tectonic - magmatic environment. In studying the hydrocarbon composition of various geological objects, untraditional for petroleum geology (igneous rocks, metamorphic rocks, mineral deposits, etc.) progressively manifested that hydrocarbons are also distributed and have the following features. Studies have shown: 1. The composition of the hydrocarbon components presented by, light hydrocarbons, heavy hydrocarbons up to including hexane, normal forms, isoforms, saturated and unsaturated hydrocarbons. 2. Hydrocarbon composition and the ratio of methane to heavy hydrocarbons corresponds to the composition of gases gas fields. 3. The composition and the ratio of hydrocarbons do not depend on genetic types of heterogeneous geological objects. 4. Gas saturation meets the prevailing structure of rocks - pores or fractures. The foregoing allows us to speak of a single source of generating and delivering hydrocarbons in the Earth's Crust, regardless of the geological situation. I.e. the presence of hydrocarbons in the Earth's Crust is UNITED! 5. From a practical point of view - virtually unconventional for hydrocarbons rock can serve as unconventional hydrocarbon resources.

    Full Text Available Developing a virtual 3D environment by using game engine is a strategy to incorporate various multimedia data into one platform. The characteristic of game engine that is preinstalled with interactive and navigation tools allows users to explore and engage with the game objects. However, most CAD and GIS applications are not equipped with 3D tools and navigation systems intended to the user experience. In particular, 3D game engines provide standard 3D navigation tools as well as any programmable view to create engaging navigation thorough the virtual environment. By using a game engine, it is possible to create other interaction such as object manipulation, non playing character (NPC interaction with player and/or environment. We conducted analysis on previous game engines and experiment on urban design project with Unity3D game engine for visualization and interactivity. At the end, we present the advantages and limitations using game technology as visual representation tool for architecture and urban design studies.

  7. The amazing unity of the Universe and its origin in the Big Bang

    van den Heuvel, Edward

    2016-01-01

    In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction ...

  8. F response and H reflex analysis of physiological unity of gravity and antigravity muscles in man.

    1977-01-01

    Observational differences between reflex (H reflex) and antidromic (F response) activation of segmental motoneurons by a peripheral electrical stimulus are described. In contrast to H reflexes, the percentage of F responses found after a series of stimuli is directly related to the pick-up field of the recording electrode consistent with this response being due to the variable activation of a small fraction of the available motoneuron pool. Despite the differing physiological mechanisms, both F responses and H reflexes can be used to demonstrate similar relative "central excitatory states" for antigravity muscles (i.e. extensors in the lower extremity and flexors in the upper extremity) and their antagonist gravity muscles. H reflexes were elicited not only in their usual location in certain antigravity muscles but also in unusual locations by length/tension changes in agonist and antagonist groups as well as by passive stretch. The data argue for the physiological unity of similarly acting gravity and antigravity muscles as well as supporting a meaningful role of group II afferents in normal segmental motoneuron pool excitability.

    Metal structures with high optical transparency and conductivity are of great importance for practical applications in optoelectronic devices. Here we investigate the transparency response of a continuous metal film sandwiched by double plasmonic nanoparticle arrays. The upper nanoparticle array shows efficient light trapping of the incident field, acting as a light input coupler, and the lower nanoparticle array shows a light release gate opening at the other side, acting as the light output coupler. The strong near-field light–matter interactions of the nano-scale separated plasmonic nanoparticles, the excitation of surface plasmon waves of the metal film, and their cooperative coupling effects result in broadband scattering cancellation and near-unity transparency (up to 96%) in the optical regime. The transparency response in such a structure can be efficiently modified by varying the gap distance of adjacent nanoparticles, dielectric environments, and the distance between the plasmonic array and the metal film. This motif may provide a new alternative approach to obtain transparent and highly conducting metal structures with potential applications in transparent conductors, plasmonic filters, and highly integrated light input and output components.

  10. Diagonal Eigenvalue Unity (DEU) code for spectral amplitude coding-optical code division multiple access

    Ahmed, Hassan Yousif; Nisar, K. S.

    2013-08-01

    Code with ideal in-phase cross correlation (CC) and practical code length to support high number of users are required in spectral amplitude coding-optical code division multiple access (SAC-OCDMA) systems. SAC systems are getting more attractive in the field of OCDMA because of its ability to eliminate the influence of multiple access interference (MAI) and also suppress the effect of phase induced intensity noise (PIIN). In this paper, we have proposed new Diagonal Eigenvalue Unity (DEU) code families with ideal in-phase CC based on Jordan block matrix with simple algebraic ways. Four sets of DEU code families based on the code weight W and number of users N for the combination (even, even), (even, odd), (odd, odd) and (odd, even) are constructed. This combination gives DEU code more flexibility in selection of code weight and number of users. These features made this code a compelling candidate for future optical communication systems. Numerical results show that the proposed DEU system outperforms reported codes. In addition, simulation results taken from a commercial optical systems simulator, Virtual Photonic Instrument (VPI™) shown that, using point to multipoint transmission in passive optical network (PON), DEU has better performance and could support long span with high data rate.

    A new two dimensional Diagonal Eigenvalue Unity (2D-DEU) code is developed for the spectral⧹spatial optical code division multiple access (OCDMA) system. It has a lower cross correlation value compared to two dimensional diluted perfect difference (2D-DPD), two dimensional Extended Enhanced Double Weight (2D-Extended-EDW) codes. Also, for the same code length, the number of users can be generated by the 2D-DEU code is higher than that provided by the others codes. The Bit Error Rate (BER) numerical analysis is developed by considering the effects of shot noise, phase induced intensity noise (PIIN), and thermal noise. The main result shows that BER is strongly affected by PIIN for the higher source power. The 2D-DEU code performance is compared with 2D-DPD, 2D-Extended-EDW and two dimensional multi-diagonals (2D-MD) codes. This comparison proves that the proposed 2D-DEU system outperforms the related codes.

    Full Text Available Jalal al-Din Rumi and Muhammad Hafez Shirazi are two of the great mystics, Sufis, writing in Persian in the 13th and 14th century. Their poetry is still an essential part of the Turkish and the Persian religious and cultural settings. The objectives of this article are to suggest a method for analyzing the poetry of Rumi and Hafez within the discipline of History of religions. The various combinations of symbols, symbolic clusters, together create a totality from which parts are taken and combined in various ways in the poems. Seldom all of them are there together, but reading some poems with various themes gives the whole combination of symbols, which has been used by the poet. It gives the picture of a Sufi setting, where the essential thing is the path to the unity with God. With it goes the Persian identity indicated in the garden of roses symbolizing paradise, kingship, justice, prosperity, the love of nature etc. Only in combination do these symbols point to the complex situation of the Persian Sufis.

    Simulations have become increasingly important for science and there is an increasing emphasis on the visualization of simulations within a Virtual Reality (VR) environment. Our group is exploring this capability as a visualization tool not just for those curious about science, but also for educational purposes for K-12 students. Using data collected in 3-D by a Time Projection Chamber (TPC), we are able to visualize nuclear and cosmic events. The Unity game engine was used to recreate the TPC to visualize these events and construct a VR application. The methods used to create these simulations will be presented along with an example of a simulation. I will also present on the development and testing of this program, which I carried out this past summer at MSU as part of an REU program. We used data from the S πRIT TPC, but the software can be applied to other 3-D detectors. This work is supported by the U.S. Department of Energy under Grant Nos.

    In this paper, we proposed and realized 3D photonic nanostructures consisting of ultra-thin graded index antireflective coatings (ARCs) and woodpile photonic crystals. The use of the integrated ARC and photonic crystal structure can achieve broadband, broad-angle near unity solar absorption. The amorphous silicon based photonic nanostructure experimentally shows an average absorption of ∼95% for λ = 400–620 nm over a wide angular acceptance of θ = 0°–60°. Theoretical studies show that a Gallium Arsenide (GaAs) based structure can achieve an average absorption of >95% for λ = 400–870 nm. Furthermore, the use of the slanted SiO{sub 2} nanorod ARC surface layer by glancing angle deposition exhibits Cassie-Baxter state wetting, and superhydrophobic surface is obtained with highest water contact angle θ{sub CB} ∼ 153°. These properties are fundamentally important for achieving maximum solar absorption and surface self-cleaning in thin film solar cell applications.

    Broadband unity absorption in graphene-insulator-metal (GIM) structures is demonstrated in the visible (VIS) and near-infrared (NIR) spectra. The spectral characteristics possess broadband absorption peaks, by simply choosing a stack of GIM, while no nanofabrication steps and patterning are required, and thus can be easily fabricated to cover a large area. The electromagnetic (EM) waves can be entirely trapped and the absorption can be greatly enhanced are verified with the finite-difference time-domain (FDTD) and rigorous coupled wave analysis (RCWA) methods. The position and the number of the absorption peak can be totally controlled by adjusting the thickness of the insulator layer. The proposed absorber maintains high absorption (above 90%) for both transverse electric (TE) and transverse magnetic (TM) polarizations, and for angles of incidence up to 80°. This work opens up a promising approach to realize perfect absorption (PA) with ultra-thin film, which could implicate many potential applications in optical detection and optoelectronic devices.

    Electronic portal imaging devices (EPIDs) are frequently used in external beam radiation therapy for dose verification purposes. The aim of this study was to investigate the dose-response characteristics of the EPID in the Unity MR-linac (Elekta AB, Stockholm, Sweden) relevant for dosimetric applications under clinical conditions. EPID images and ionization chamber (IC) measurements were used to study the effects of the magnetic field, the scatter generated in the MR housing reaching the EPID, and inhomogeneous attenuation from the MR housing. Dose linearity and dose rate dependencies were also determined. The magnetic field strength at EPID level did not exceed 10 mT, and dose linearity and dose rate dependencies proved to be comparable to that on a conventional linac. Profiles of fields, delivered with and without the magnetic field, were indistinguishable. The EPID center had an offset of 5.6 cm in the longitudinal direction, compared to the beam central axis, meaning that large fields in this direction will partially fall outside the detector area and not be suitable for verification. Beam attenuation by the MRI scanner and the table is gantry angle dependent, presenting a minimum attenuation of 67% relative to the 90° measurement. Repeatability, observed over two months, was within 0.5% (1 SD). In order to use the EPID for dosimetric applications in the MR-linac, challenges related to the EPID position, scatter from the MR housing, and the inhomogeneous, gantry angle-dependent attenuation of the beam will need to be solved.

    2015-01-01

    This project centres on the development of a virtual nuclear facility environment to assist non-proliferation and nuclear arms control practitioners - including researchers, negotiators, or inspectors - in developing and refining a verification system and secure chain of custody of material or equipment. The platform for creating the virtual facility environment is the Unity 3D game engine. This advanced platform offers both the robust capability and flexibility necessary to support the design goals of the facility. The project also employs Trimble SketchUp and Blender 3D for constructing the model components. The development goal of this phase of the project was to generate a virtual environment that includes basic physics in which avatars can interact with their environment through actions such as picking up objects, operating vehicles, dismantling a warhead through a spherical representation system, opening/closing doors through a custom security access system, and conducting CCTV surveillance. Initial testing of virtual radiation simulation techniques was also explored in preparation for the next phase of development. Some of the eventual utilities and applications for this platform include: 1. conducting live multi-person exercises of verification activities within a single, shared virtual environment, 2. refining procedures, individual roles, and equipment placement in the contexts of non-proliferation or arms control negotiations 3. hands on training for inspectors, and 4. a portable tool/reference for inspectors to use while carrying out inspections. This project was developed under the Multilateral Verification Project, led by the Verification Research, Training and Information Centre (VERTIC) in the United Kingdom, and financed by the Norwegian Ministry of Foreign Affairs. The environment was constructed at the Vienna Center for Disarmament and Non-Proliferation (VCDNP). (author)

    Crude prevalence rates of spondylolysis were estimated in skeletal populations from various periods. There was a steady increase in prevalence from 3.74% in Romano-British to 5.08% in medieval populations, but the rate fell considerably to 1.42% in a population from an 18th/19th century context. This trend was not statistically significant, however. The male/female ratio was approximately unity until the 18th/19th century when the expected male excess appeared. The lesions predominantly affected L5 and all were isthmic in type. Of the total of 52 cases, only four were unilateral. One occurred in the fourth cervical vertebra. There were few complications; spondylolisthesis was noted in four cases and in three there were osteoarthritic changes on the superior margin of the displaced lamina. PMID:1941859

    The previously developed kinetic model for droplet heating and evaporation into a high pressure air is generalised to take into account the combined effects of inelastic collisions between molecules in the kinetic region, a non-unity evaporation coefficient and temperature gradient inside droplets. It is pointed out that for the parameters typical for Diesel engine-like conditions, the heat flux in the kinetic region is a linear function of the vapour temperature at the outer boundary of this region, but practically does not depend on vapour density at this boundary for all models, including and not including the effects of inelastic collisions, and including and not including the effects of a non-unity evaporation coefficient. For any given temperature at the outer boundary of the kinetic region the values of the heat flux are shown to decrease with increasing numbers of internal degrees of freedom of the molecules. The rate of this decrease is strong for small numbers of these degrees of freedom but negligible when the number of these degrees exceeds 20. This allows us to restrict the analysis to the first 20 arbitrarily chosen degrees of freedom of n-dodecane molecules when considering the effects of inelastic collisions. The mass flux at this boundary decreases almost linearly with increasing vapour density at the same location for all above-mentioned models. For any given vapour density at the outer boundary of the kinetic region the values of the mass flux are smaller for the model, taking into account the contribution of internal degrees of freedom, than for the model ignoring these degrees of freedom. It is shown that the effects of inelastic collisions lead to stronger increase in the predicted droplet evaporation time in Diesel engine-like conditions relative to the hydrodynamic model, compared with the similar increase predicted by the kinetic model considering only elastic collisions. The effects of a non-unity evaporation coefficient are shown to be

  10. [Manpower migrations and Arab unity: the challenges of the Iraqi model].

    Science.gov (United States)

    Roussillon, A

    1985-01-01

    the presence of large numbers of foreign workers not only to the countries employing them but to the Arab nation as a whole allows Iraq to criticize the migration policies of the Gulf oil exporters, which are increasingly favoring more productive labor from Asian countries and which cede much of the authority to select and admit workers to private concerns. The evolution of Iraq's policy demonstrates the concern of its governing party with reconciling its Arab identity and its analysis of international power relations with consolidation of its own position internally and in the Arab world as a whole. The labor policy of the oil exporters exposes their countries and thus the Arab world to the possibility of sabotage and to demographic overpowering of ethnic and cultural identity. Interpretations differ as to whether the Iraqi model has led to a better deployment of labor and as to its theoretical contribution to pan-Arab unity, given the diverging interests of the individual states concerned.

    Full Text Available An in depth investigation was conducted on the possibility of literature employed to enhance cohesion, sustainable unity, national stability and security of lives and property in the contemporary Nigeria. These three elements- Unity, national stability and security of lives and property are considered the key-pillars of a modern state, the absence of which render the Country volatile and uninhabitable. The contemporary Nigeria lacks these elements in a large dose, thereby rendering it a country without peace and security. This has been the root cause of the current nationwide agitation for a national conference required to define the future for a country that has existed for a century, but still grappling unsuccessfully, with the problems of nationhood. This paper identified the cause of the problems to arise from the multi-ethnic composition of the one-hundred and seventy million people and over three hundred different ethnic nationals of Nigeria. The fact of uniting so many ethnic groups into one country is not peculiar to Nigeria, as many other countries have a similar composition.

  13. A unified computational model of the development of object unity, object permanence, and occluded object trajectory perception.

    2010-12-01

    The perception of the unity of objects, their permanence when out of sight, and the ability to perceive continuous object trajectories even during occlusion belong to the first and most important capacities that infants have to acquire. Despite much research a unified model of the development of these abilities is still missing. Here we make an attempt to provide such a unified model. We present a recurrent artificial neural network that learns to predict the motion of stimuli occluding each other and that develops representations of occluded object parts. It represents completely occluded, moving objects for several time steps and successfully predicts their reappearance after occlusion. This framework allows us to account for a broad range of experimental data. Specifically, the model explains how the perception of object unity develops, the role of the width of the occluders, and it also accounts for differences between data for moving and stationary stimuli. We demonstrate that these abilities can be acquired by learning to predict the sensory input. The model makes specific predictions and provides a unifying framework that has the potential to be extended to other visual event categories. Copyright © 2010 Elsevier Inc. All rights reserved.

    2016-10-01

    This paper investigates the ability to develop synthetic scenes in an image generation tool, E-on Vue, and a gaming engine, Unity 3D, which can be used to generate synthetic imagery of target objects across a variety of conditions in land environments. Developments within these tools and gaming engines have allowed the computer gaming industry to dramatically enhance the realism of the games they develop; however they utilise short cuts to ensure that the games run smoothly in real-time to create an immersive effect. Whilst these short cuts may have an impact upon the realism of the synthetic imagery, they do promise a much more time efficient method of developing imagery of different environmental conditions and to investigate the dynamic aspect of military operations that is currently not evaluated in signature analysis. The results presented investigate how some of the common image metrics used in target acquisition modelling, namely the Δμ1, Δμ2, Δμ3, RSS, and Doyle metrics, perform on the synthetic scenes generated by E-on Vue and Unity 3D compared to real imagery of similar scenes. An exploration of the time required to develop the various aspects of the scene to enhance its realism are included, along with an overview of the difficulties associated with trying to recreate specific locations as a virtual scene. This work is an important start towards utilising virtual worlds for visible signature evaluation, and evaluating how equivalent synthetic imagery is to real photographs.

    2014-12-01

    The main objectives of the paper are to (1) present an overview of nonlocal integral elasticity and Aifantis gradient elasticity theory and (2) discuss the application of partition of unity methods to study the response of low-dimensional structures. We present different choices of approximation functions for gradient elasticity, namely Lagrange intepolants, moving least-squares approximants and non-uniform rational B-splines. Next, we employ these approximation functions to study the response of nanobeams based on Euler-Bernoulli and Timoshenko theories as well as to study nanoplates based on first-order shear deformation theory. The response of nanobeams and nanoplates is studied using Eringen's nonlocal elasticity theory. The influence of the nonlocal parameter, the beam and the plate aspect ratio and the boundary conditions on the global response is numerically studied. The influence of a crack on the axial vibration and buckling characteristics of nanobeams is also numerically studied.

    Korucu, Ayse; Miller, Richard

    2016-11-01

    Direct numerical simulations (DNS) of temporally developing shear flames are used to investigate both equation of state (EOS) and unity-Lewis (Le) number assumption effects in hydrocarbon flames at elevated pressure. A reduced Kerosene / Air mechanism including a semi-global soot formation/oxidation model is used to study soot formation/oxidation processes in a temporarlly developing hydrocarbon shear flame operating at both atmospheric and elevated pressures for the cubic Peng-Robinson real fluid EOS. Results are compared to simulations using the ideal gas law (IGL). The results show that while the unity-Le number assumption with the IGL EOS under-predicts the flame temperature for all pressures, with the real fluid EOS it under-predicts the flame temperature for 1 and 35 atm and over-predicts the rest. The soot mass fraction, Ys, is only under-predicted for the 1 atm flame for both IGL and real gas fluid EOS models. While Ys is over-predicted for elevated pressures with IGL EOS, for the real gas EOS Ys's predictions are similar to results using a non-unity Le model derived from non-equilibrium thermodynamics and real diffusivities. Adopting the unity Le assumption is shown to cause misprediction of Ys, the flame temperature, and the mass fractions of CO, H and OH.

    The main objective of this paper is to discuss on the effectiveness of visualising terrain draped with Unmanned Aerial Vehicle (UAV) images generated from different contour intervals using Unity 3D game engine in online environment. The study area that was tested in this project was oil palm plantation at Sintok, Kedah. The contour data used for this study are divided into three different intervals which are 1m, 3m and 5m. ArcGIS software were used to clip the contour data and also UAV images data to be similar size for the overlaying process. The Unity 3D game engine was used as the main platform for developing the system due to its capabilities which can be launch in different platform. The clipped contour data and UAV images data were process and exported into the web format using Unity 3D. Then process continue by publishing it into the web server for comparing the effectiveness of different 3D terrain data (contour data) draped with UAV images. The effectiveness is compared based on the data size, loading time (office and out-of-office hours), response time, visualisation quality, and frame per second (fps). The results were suggest which contour interval is better for developing an effective online 3D terrain visualisation draped with UAV images using Unity 3D game engine. It therefore benefits decision maker and planner related to this field decide on which contour is applicable for their task.

    2012-10-01

    Full Text Available The term ‘worldview’ harbours different dimensions that are not always clearly distinguished. A worldview can be considered to be a personal matter, but it may also be a more collective phenomenon, as it can manifest itself for example within a certain sphere of life (e.g. politics or economics as a full-blown ideology or a more implicit ‘embedded worldview’. A second distinction can be made between the dimension of a deep, existential commitment and that of an encompassing mental framework, between spiritual inspiration and a more or less intellectually coherent system. There may be tensions between these various dimensions. Having a worldview as a person may imply being in conflict with other worldviews that are embodied in certain social fields. How can people deal with these conflicts? One can easily be seduced to avoid the conflicts and to shift gears between them. With the credit crisis and economics used as an illustration, this article explores some of the techniques that people – consciously, semi-consciously or unconsciously – may employ to navigate the differences between various social domains and their inherent worldviews. In order to support people to regain some unity, the notion of worldview may still be helpful, but interpreted primarily as ‘deep commitment’.

  10. Superconductivity and fusion energy—the inseparable companions

    Science.gov (United States)

    Bruzzone, Pierluigi

    2015-02-01

    Although superconductivity will never produce energy by itself, it plays an important role in energy-related applications both because of its saving potential (e.g., power transmission lines and generators), and its role as an enabling technology (e.g., for nuclear fusion energy). The superconducting magnet’s need for plasma confinement has been recognized since the early development of fusion devices. As long as the research and development of plasma burning was carried out on pulsed devices, the technology of superconducting fusion magnets was aimed at demonstrations of feasibility. In the latest generation of plasma devices, which are larger and have longer confinement times, the superconducting coils are a key enabling technology. The cost of a superconducting magnet system is a major portion of the overall cost of a fusion plant and deserves significant attention in the long-term planning of electricity supply; only cheap superconducting magnets will help fusion get to the energy market. In this paper, the technology challenges and design approaches for fusion magnets are briefly reviewed for past, present, and future projects, from the early superconducting tokamaks in the 1970s, to the current ITER (International Thermonuclear Experimental Reactor) and W7-X projects and future DEMO (Demonstration Reactor) projects. The associated cryogenic technology is also reviewed: 4.2 K helium baths, superfluid baths, forced-flow supercritical helium, and helium-free designs. Open issues and risk mitigation are discussed in terms of reliability, technology, and cost.

    The coastal population of British Columbia is projected to increase by a million people over the next 20 years. Population growth in the region will increase pressure on the environment through land-use changes and water demand, and the discharge of wastes and pollutants. Changes to the environment will have an impact on industries such as forestry, fishing, and tourism that depend on healthy ecosystems. Six technical papers were presented in this volume as part of a project reporting on the coastal environment of British Columbia. The volume was compiled to help in the future-decision making processes in the province. Reporting for the project focused on a region extending westward from the height of the Coast Mountains, and included the marine area within Canada's 200-mile limit. Papers were presented on the following topics: (1) population and economic activity; (2) climate change; (3) industrial contaminants; (4) ecosystem protection; (5) bio-diversity; and (6) fisheries. Each of the 6 papers provided an overview of issues related to their topic, a set of indicators, and a summary of results. refs., tabs., figs

    There are several examples of bipartite entangled states of continuous variables for which the existing criteria for entanglement using the inequalities involving the second-order moments are insufficient. We derive new inequalities involving higher order correlation, for testing entanglement in non-Gaussian states. In this context, we study an example of a non-Gaussian state, which is a bipartite entangled state of the form Ψ(x a , x b ) ∝ (αx a + βx b ) e -(x a 2 +x b 2 )/2 . Our results open up an avenue to search for new inequalities to test entanglement in non-Gaussian states

  16. Endoscopy and sedation: an inseparable binomial for the gastroenterologist.

    Science.gov (United States)

    Crespo, Javier; Terán, Álvaro

    2018-04-01

    The development of endoscopy and its increasing demand among the population have led to a growing need for propofol-based sedation techniques. Benefit is indisputable for both patients and endoscopists, but some aspects require considering the "who" and "how" of sedation as related to safety and health care costs. Propofol is first-choice in endoscopy for the European Society of Gastrointestinal Endoscopy because of its fast onset of action and short half-life, and many reports exist on its safety when used by gastroenterologists rather than anesthesiologists. In this issue of REED several originals support the efficiency and safety of propofol even for complex, high-risk, or protracted procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and enteroscopy. Propofol may be safely and effectively administered by a team with specific skills acquired through education and using a specific procedure. However, difficulties arise in real-world clinical practice that preclude such training, which in Spain should be included in the MIR (médico interno residente) specialization program curriculum. The Comisión Nacional de Digestivo (Spanish National Commission on Digestive Diseases), sensitive to this training gap, has included in their latest version of the MIR program (under assessment) four additional competences, with number 145 (training in deep sedation) being most relevant here. In addition, the Spanish Society of Gastrointestinal Endoscopy (SEED) has invested significant efforts in sedation training, with over 50 courses on sedation for endoscopists and nurses. Continuing education and training in this field (for instance, refresher courses on advanced cardiopulmonary resuscitation) should be a goal for all endoscopy units. Because of the diversity found among hospitals, with single or multiple endoscopy rooms, efforts should be made to persuade those in charge of gastroenterology and anesthesiology departments to establish the necessary care circuits in order to guarantee patient safety by developing accurate protocols and promoting consensus among the scientific societies involved (Spanish Society for Digestive Diseases [SEPD], SEED and Spanish Society of Anaesthesiology, Resuscitation and Pain Management [SEDAR]) and their respective national commissions.

    Full Text Available For starting a long term programmes in Croatian animal production, formation of "economic unities" is necessary. Presentation and explanation of production and trade unity for animal production and marketing with subjects and phases is given here. It is pointed out that production of slaughter animals and meat is key interest of market and economic policy as well as of development of agricultural country. It seems that production and trade of meat in Croatia is not organized enough in overall market competition and in meat processing. Creating the economic unity of production and trade of slaughter animals can help in relative fast and efficient solving of problems accumulated in agriculture, especialy in meat production (PIK Vrbovec, Danica, Bejle etc. For initiating and getting in function the phases of production and trade of slaughter animals and meat, proper legislation should be introduced. This legislation should comprehencively define the idea of agricultural economy as a subject of legislative and normisation acts for overall, process and market oriented functioning of multidisciplinary agricultural systems. Additionaly, law on trade of slaughter animals, meat and agricultural products should be introduced in order to form a market and determine the share and obligations of certain participants in structure of such market.

    Porfert, A R; Rosenfield, D B

    1978-01-01

    The prevalence of stuttering in a university population was 2.1%; 3.4% were former stutterers. More men than women stuttered. Right handed female stutterers were less likely to have "lost" their stutter than were right handed males. Stutterers, past stutterers, and questionable stutterers all had a family history of stuttering. The significant prevalence of stuttering, the increased prevalence among males, the lack of a decline of this disorder over the past few decades despite the increased number of speech clinicians and data concerning handedness, emphasise the need to investigate organic causes of stuttering.

    This PhD thesis asks how we can conceptualize the current separation doctrine of religion and politics in a country like Denmark, where the structure of the established church and peoplehood overlap. In order to answer this question, Hans Bruun Dabelsteen maps the current discussion of secularism...... into the principle of treating everybody equally (with religious freedom, equality and Danish peoplehood as the most important principles adjacent to secularism). In a study of the historical roots of the separation doctrine and two current policy cases (same-sex marriage and reforms of church governance...

    The author suggest that the discovery of ''hidden'' symmetries in the subatomic world will, in due time succeed in uniting the strong and weak nuclear forces and the electromagnetic force (already successfully united in the Standard Model) with the fourth universal force, gravity, to produce a ''unified theory of everything''. Concepts such as groups, in the context of quantum field theory, supersymmetry and superstrings are explained to back this contention. Recent work on the nature of electromagnetic duality, may, it is argued, increase our comprehension to a level where ''theories of everything'' may emerge. (UK)

    One of the main ways in transmitting parasites to humans is through consuming contaminated raw vegetables. The aim of this study was to evaluate the prevalence of parasitological contamination (helminthes eggs, Giardia and Entamoeba histolytica cysts) of salad vegetables sold at supermarkets and street vendors in Amman and Baqa’a – Jordan. A total of 133 samples of salad vegetables were collected and examined for the prevalence of parasites. It was found that 29% of the samples were contaminated with different parasites. Of the 30 lettuce, 33 tomato, 42 parsley and 28 cucumber samples examined the prevalence of Ascaris spp. eggs was 43%, 15%, 21% and 4%; Toxocara spp. eggs was 30%, 0%, 0% and 4%; Giardia spp. cysts was 23%, 6%, 0% and 0%; Taenia/Echinococcus eggs was 20%, 0%, 5% and 0%; Fasciola hepatica eggs was 13%, 3%, 2% and 0%; and E. histolytica cysts was 10%, 6%, 0% and 0%, respectively. There was no significant difference in the prevalence of parasite in salad vegetables either between supermarkets and street vendors, or between Amman and Baqa’a, Ascaris spp. was found to be the highest prevalent parasite in salad vegetables from supermarkets and street vendors and from Amman and Baqa’a. Our results pointed out that, the parasitic contamination of salad vegetables found in our study might be caused by irrigating crops with faecal contaminated water. We concluded that salad vegetables sold in Amman and Baqa’a may cause a health risk to consumers.

The article investigates historical legal, theoretical-methodological and constitutional-legal problems of the formation and functioning of the institute of the head of state.The purpose of the study is to show how the constitutional functions of the head of state concretize his powers.The study is based on the use of methods of analysis and synthesis, historical legal, formal legal, comparative legal methods, scientific abstraction.The main scientific results. The authors summarize that the historical and legal analysis shows the key role of the head of state in the mechanism of ensuring state unity and law and order. Reality testifies the fact that the role of the President of the Russian Federation creates sufficient constitutional and legal grounds and conditions for the consolidated work of all state authorities, including law enforcement agencies, in the direction of ensuring the unity of state power and constitutional law and order. The indicated directions are in many ways identical, organically interrelated and interdependent, systematically define the main lines of activity of the head of state, contributing to the improvement of the constitutional and legal mechanism for ensuring the rule of law in general. Firstly, the Constitution of the Russian Federation contains only the basic powers of the President of the Russian Federation, which are substantially expanded by the legislator and presidential decrees. Secondly, the President has so-called “hidden”, discretionary powers that are not directly enshrined in the Constitution of the Russian Federation, implicit in it and stem from the sense of presidential functions that manifest themselves in unforeseen extraordinary circumstances. Thus, the constitutional design of a strong presidential power allows the President of the Russian Federation to ensure the unity of the executive power and the exercise of the powers of the federal government throughout the territory of

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2008v7n2p137This paper systematically discusses Kant´s argumentation in the Canon of the Critique of pure reason on the matter of the establishment of the practical use and its outcomes for the problem of the unity of reason. Bearing in mind that there is much disagreement in the literature, not only as to the specificity and function of the chapter of the Canon wi thin the various moments of Kant´s philosophy, but also as to its critical importance, the approach centers essentially on Kant´s own argumentation. The aim of this paper is to show that the Canon anticipates an important thesis of the Critique of Practical Reason, i.e., the self-sufficient legitimation of the practical use of reason in relation to its theoretical use, Moreover, is demonstrated that there are important systenatic differences between Kant´s argumentation in the Canon and in the second Critique, which lead to the uniqueness of the treatment of the problem of the unity of reason in the former text. The first part of the paper briefly presents Kant´s position in the pre-critical period on the legitimation of the practical use of reason. Thereafter, it is sustained that Kant´s search in the Canon for a "source of positive cognition" is particularly connected with his critical thesis of a self-sufficient establishment in the Canon. It is argued that, notwithstanding the anticipation of the refered critical thesis, the establishment of the practical use of reason in the Canon requires a theological consideration of morality. The third part of the paper deals with the problem of the unity of theorical and practical uses of reason in position on the establishment of the practical use reason. I come to the conclusion that the Canon guaranteed by means of a transition from the practical to the theoretical use of reason.

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

  12. Bidentate Ligand-passivated CsPbI3 Perovskite Nanocrystals for Stable Near-unity Photoluminescence Quantum Yield and Efficient Red Light-emitting Diodes

    KAUST Repository

    Pan, Jun

    2017-12-17

    Although halide perovskite nanocrystals (NCs) are promising materials for optoelectronic devices, they suffer severely from chemical and phase instabilities. Moreover, the common capping ligands like oleic acid and oleylamine that encapsulate the NCs will form an insulating layer, precluding their utility in optoelectronic devices. To overcome these limitations, we develop a post-synthesis passivation process for CsPbI3 NCs by using a bidentate ligand, namely 2,2’-Iminodibenzoic acid. Our passivated NCs exhibit narrow red photoluminescence with exceptional quantum yield (close to unity) and substantially improved stability. The passivated NCs enabled us to realize red light-emitting diodes (LEDs) with 5.02% external quantum efficiency and 748 cd/m2 luminance, surpassing by far LEDs made from the non-passivated NCs.

    2016-10-01

    Full Text Available In this paper, the author questions the role of musical genre presented on the Eurovision Song Contest in the context of the unity in diversity concept, recognized as one of the markers of European cultural identity. Interpretation of this concept in sociological theory is presented while arguing that it could be understood in the history of the contest. A broader view on genres presented in the first decades of the contest is offered, before focusing on a case study of Finland’s 2006 winning song. Although unusual in a purely musical sense in the context of the ESC, it is argued that this entry is more understandable when more determinants of performing European identity on the ESC stage are included in the interpretation, and that music serves as only one of those determinants and thus should be interpreted as cultural discoursive practice.

    2017-05-01

    Congenital amusia (commonly known as tone deafness) is a lifelong musical disorder that affects 4% of the population according to a single estimate based on a single test from 1980. Here we present the first large-based measure of prevalence with a sample of 20 000 participants, which does not rely on self-referral. On the basis of three objective tests and a questionnaire, we show that (a) the prevalence of congenital amusia is only 1.5%, with slightly more females than males, unlike other developmental disorders where males often predominate; (b) self-disclosure is a reliable index of congenital amusia, which suggests that congenital amusia is hereditary, with 46% first-degree relatives similarly affected; (c) the deficit is not attenuated by musical training and (d) it emerges in relative isolation from other cognitive disorder, except for spatial orientation problems. Hence, we suggest that congenital amusia is likely to result from genetic variations that affect musical abilities specifically.

  1. How prevalent is 'food addiction'?

    Directory of Open Access Journals (Sweden)

    Adrian eMeule

    2011-11-01

    Full Text Available Increasing evidence suggests that binge eating-related disorders could be related to addiction-like eating patterns due to the addictive potential of hyperpalatable foods. Subsequently, important implications have been derived for treatment of those disorders and even political actions. However, studies on the prevalence of food addiction are rare. Few recent studies investigated addictive eating in children, adolescents, and adults. This mini-review presents these first attempts to assess addictive eating and how prevalent addictive eating patterns were in the respective studies. It is concluded that the prevalence of food addiction is increased in obese individuals and even more so in obese patients with binge eating disorder. However, prevalence of food addiction is not sufficient to account for the obesity epidemic. Conversely, an arguably high prevalence of food addiction can also be found in under-, normal-, and overweight individuals. Future studies may investigate which factors are associated with addictive eating in non-obese individuals.

  3. Prevalence of occupational disease

    Newhouse, M.L.

    1976-12-01

    When discussing the prevalence of occupational disease, both the prescribed diseases and the diseases where occupation has an important etiological component should be considered. Available statistics indicate that there has been a substantial improvement in the control of important prescribed diseases such as lead poisoning and pneumoconiosis. In the United Kingdom in 1900 there were 1000 cases of lead poisoning with 38 fatalities. This number decreased to 49 cases in 1956 when the number again increased due to a change from clinical diagnosis to diagnosis on biochemical evidence. The number of cases of coal workers' pneumoconiosis has declined since the 1950s but the number of coal miners has also been reduced by more than /sup 1///sub 3/. Industrial dermatitis is still a considerable problem. Vibration induced white fingers was mentioned as a disease with a very large occupational component but which for a variety of reasons is not prescribed for industrial injury benefit. Illnesses due to injuries to the back, to sciatica, disc disease or lumbago cause a very large amount of sickness and are often associated with heavy manual labor particularly if an awkward posture has to be adopted for the job. The average absence after a back injury in the London Docks was 61 days. Chronic bronchitis is the biggest single cause of sickness absence. Many studies have shown that the etiology is multifactorial but that hard physical work and a dusty environment in the work place are important adverse factors. Improved control of the working environment and methods of work may influence the development of chronic disease in the older worker.

    Steep-slope transistors allow to scale down the supply voltage and the energy per computed bit of information as compared to conventional field-effect transistors (FETs), due to their sub-60 mV/decade subthreshold swing at room temperature. Currently pursued approaches to achieve such a subthermionic subthreshold swing consist in alternative carrier injection mechanisms, like quantum mechanical band-to-band tunneling (BTBT) in Tunnel FETs or abrupt phase-change in metal-insulator transition (MIT) devices. The strengths of the BTBT and MIT have been combined in a hybrid device architecture called phase-change tunnel FET (PC-TFET), in which the abrupt MIT in vanadium dioxide (VO 2 ) lowers the subthreshold swing of strained-silicon nanowire TFETs. In this work, we demonstrate that the principle underlying the low swing in the PC-TFET relates to a sub-unity body factor achieved by an internal differential gate voltage amplification. We study the effect of temperature on the switching ratio and the swing of the PC-TFET, reporting values as low as 4.0 mV/decade at 25 °C, 7.8 mV/decade at 45 °C. We discuss how the unique characteristics of the PC-TFET open new perspectives, beyond FETs and other steep-slope transistors, for low power electronics, analog circuits and neuromorphic computing.

    Full Text Available The Volta Grande Environmental Unity represents one of the few remnants of Cerrado protected by areserve in the Triângulo Mineiro region, municipalities of Conceição das Alagoas (19°55' S, 48°23' W andMiguelópolis (20°12' S, 48°03' W, in the states of Minas Gerais and São Paulo, respectively. The mammalian fauna ofthis reserve was inventoried between 2003 and 2004 to generate estimates about taxonomic composition, richness, andabundance of species. A sampling effort of 832 trapping-nights resulted in 24 species recorded. Cumulative curvessuggest that the overall inventory is not complete and that more species are likely to be registered. The majority ofspecies recorded is widespread along the Cerrado, but include some noteworthy records of endangered species, such asthe Giant anteater (Myrmecophaga tridactyla and the Manned wolf (Chrysocyon brachyurus. The record of thearboreal cricetid rodent Oecomys bicolor represents a slight extension of the southeastern limit of its distribution.

    Outer-shell s0/p0 orbital mixing with d10 orbitals and symmetry reduction upon cupriphication of cyclic trinuclear trigonal-planar gold(I) complexes are found to sensitize ground-state Cu(I)–Au(I) covalent bonds and near-unity phosphorescence quantum yields. Heterobimetallic Au4Cu2 {[Au4(μ-C2,N3-EtIm)4Cu2(µ-3,5-(CF3)2Pz)2], (4a)}, Au2Cu {[Au2(μ-C2,N3-BzIm)2Cu(µ-3,5-(CF3)2Pz)], (1) and [Au2(μ-C2,N3-MeIm)2Cu(µ-3,5-(CF3)2Pz)], (3a)}, AuCu2 {[Au(μ-C2,N3-MeIm)Cu2(µ-3,5-(CF3)2Pz)2], (3b) and [Au(μ-C2,N3-EtIm)Cu2(µ-3,5-(CF3)2Pz)2], (4b)} and stacked Au3/Cu3 {[Au(μ-C2,N3-BzIm)]3[Cu(µ-3,5-(CF3)2Pz)]3, (2)} form upon reacting Au3 {[Au(μ-C2,N3-(N-R)Im)]3 ((N-R)Im = imidazolate; R = benzyl/methyl/ethyl = BzIm/MeIm/EtIm)} with Cu3 {[Cu(μ-3,5-(CF3)2Pz)]3 (3,5-(CF3)2Pz = 3,5-bis(trifluoromethyl)pyrazolate)}. The crystal structures of 1 and 3a reveal stair-step infinite chains whereby adjacent dimer-of-trimer units are noncovalently packed via two Au(I)⋯Cu(I) metallophilic interactions, whereas 4a exhibits a hexanuclear cluster structure wherein two monomer-of-trimer units are linked by a genuine d10–d10 polar-covalent bond with ligand-unassisted Cu(I)–Au(I) distances of 2.8750(8) Å each—the shortest such an intermolecular distance ever reported between any two d10 centers so as to deem it a “metal–metal bond” vis-à-vis “metallophilic interaction.” Density-functional calculations estimate 35–43 kcal/mol binding energy, akin to typical M–M single-bond energies. Congruently, FTIR spectra of 4a show multiple far-IR bands within 65–200 cm−1, assignable to vCu-Au as validated by both the Harvey–Gray method of crystallographic-distance-to-force-constant correlation and dispersive density functional theory computations. Notably, the heterobimetallic complexes herein exhibit photophysical properties that are favorable to those for their homometallic congeners, due to threefold-to-twofold symmetry reduction, resulting in cuprophilic

    Glenohumeral arthritis secondary to massive rotator cuff tear presents with a superior displacement and femoralization of the humeral head with coracoacromial arch acetabularization. The purpose of this study was to establish prevalence of rotator cuff tear artropathy (CTA) at our institution. Four hundred electronic records were reviewed from which we identified 136 patients with rotator cuff tears. A second group was composed with patients with massive cuff tears that were analized and staged by the Seebauer cuff tear arthropathy classification. Thirty four patients with massive rotator cuff tears were identified, 8 male and 26 female (age 60.1 ± 10.26 years). Massive rotator cuff tear prevalence was 25%. CTA prevalence found in the rotator cuff group was 19 and 76% in the massive cuff tears group. Patients were staged according to the classification with 32% in stage 1a, 11% 1b, 32% 2a and 0% 2b. CTA prevalence in patients with rotator cuff tears and massive cuff tears is higher than the one reported in American population. We consider that a revision of the Seebauer classification to be appropriate to determine its reliability.

    A hydrogeochemical study has been undertaken on the phreatic system of the coastal area included between Fiumi Uniti and Bevano rivers (in the southern part of the Po plain, near the city of Ravenna) within the framework of the CIRCLE-ERANET project WATERKNOW on the effects of climate change on the mediterranean catchments. It is one of the first attempt in the area to characterize the shallow groundwater water system and to investigate if the arsenic anomaly, known in deeper groundwater (about 100 µg/l according to recent Annual Groundwater Quality Reports of Emilia-Romagna Region), occurs also in the phreatic system. The coastal part of the Po plain consists of a low-lying and mechanically-drained farmland further from the sea and of a narrow belt of dunes and pine forests in the backshore area. The study area is recognized as a protected area at european (ZPS and SIC, site code number: IT 14070009), national and regional level (Po delta Park area). As a result of an intensive exploitation of coastal aquifers for agricultural, industrial, and civil uses, both the phreatic aquifer and the surface waters (drainage ditches and ponds) have been contaminated by seawater and by deeper groundwater. Samples representative of the top of the water table were collected in Summer 2008 in 22 auger-holes and in 3 shallow piezometers (6 m deep) documenting the deeper layers of the phreatic groundwater system. Temperature, electrical conductivity, pH and Eh of the groundwater and of the surface water were measured on site using portable instruments. Samples were filtered directly in the field, an aliquot was acidified with diluted HCl for metal analysis. Cations were determined by Flame Atomic Absorption (thermo S-series spectrometer), anions by ion chromatography (Dionex ICS-90), Fe, As, Si, B by ICP-OES (Thermo iCAP6000). The data collected in the field show that a fresh groundwater lens is still present at the top of the phreatic aquifer in the backshore area and that the

  4. Food allergy: is prevalence increasing?

    2017-03-01

    It is generally accepted that the prevalence of food allergy has been increasing in recent decades, particularly in westernised countries, yet high-quality evidence that is based on challenge confirmed diagnosis of food allergy to support this assumption is lacking because of the high cost and potential risks associated with conducting food challenges in large populations. Accepting this caveat, the use of surrogate markers for diagnosis of food allergy (such as nationwide data on hospital admissions for food anaphylaxis or clinical history in combination with allergen-specific IgE (sIgE) measurement in population-based cohorts) has provided consistent evidence for increasing prevalence of food allergy at least in western countries, such as the UK, United States and Australia. Recent reports that children of East Asian or African ethnicity who are raised in a western environment (Australia and United States respectively) have an increased risk of developing food allergy compared with resident Caucasian children suggest that food allergy might also increase across Asian and African countries as their economies grow and populations adopt a more westernised lifestyle. Given that many cases of food allergy persist, mathematical principles would predict a continued increase in food allergy prevalence in the short to medium term until such time as an effective treatment is identified to allow the rate of disease resolution to be equal to or greater than the rate of new cases. © 2017 Royal Australasian College of Physicians.

    Pedophilia is a disorder of sexual preference that increases the risk for committing sexual offenses against children. Consequently, pedophilia is not only relevant in psychiatric therapy and prognostics, but also greatly influences the public attitude towards criminality. Public opinion seems to equate pedophilia with child sexual abuse and vice versa which leads to stigmatization of patients and may impede treatment. The present paper provides information on recent studies on the potential origins of the disorder and introduces new diagnostic methods. Moreover, the article presents estimates on the prevalence of pedophilic sexual interest.

    It is anticipated that in the future, livestock will be exposed to a greater risk of infection from parasitic diseases. Therefore, future breeding strategies for livestock, which are generally long-term strategies for change, should target animals adaptable to environments with a high parasitic load. Covariance components were estimated in the present study for a selection of dairy and beef performance traits over herd-years differing in Fasciola hepatica load using random regression sire models. Herd-year prevalence of F. hepatica was determined by using F. hepatica-damaged liver phenotypes which were recorded in abattoirs nationally. The data analyzed consisted up to 83,821 lactation records from dairy cows for a range of milk production and fertility traits, as well as 105,054 young animals with carcass-related information obtained at slaughter. Reaction norms for individual sires were derived from the random regression coefficients. The heritability and additive genetic standard deviations for all traits analyzed remained relatively constant as herd-year F. hepatica prevalence gradient increased up to a prevalence level of 0.7; although there was a large increase in heritability and additive genetic standard deviation for milk and fertility traits in the observed F. hepatica prevalence levels >0.7, only 5% of the data existed in herd-year prevalence levels >0.7. Very little rescaling, therefore, exists across differing herd-year F. hepatica prevalence levels. Within-trait genetic correlations among the performance traits across different herd-year F. hepatica prevalence levels were less than unity for all traits. Nevertheless, within-trait genetic correlations for milk production and carcass traits were all >0.8 for F. hepatica prevalence levels between 0.2 and 0.8. The lowest estimate of within-trait genetic correlations for the different fertility traits ranged from -0.03 (SE = 1.09) in age of first calving to 0.54 (SE = 0.22) for calving to first service

    The Italian political unification is a process starting in 1861. The next ten years, until the freeing of Rome, are a period of strong changes because the the new nation starts by heavier backwardness conditions compared to other European nations.

    The basic conditionings that bound the new nation are summarized in some causes: an underdeveloped economic system where there are areas of industrial development; a significant shortage of mineral and energy resources; and an urban structure that is still that of the sixteenth century, the last brightness period of the Italian cities. The same internal communication system is composed of a basic road network which is still one of Roman origin and of isolated sections of rail network, with few links among the pre-unity nations.

    Particular attention should be paid on the impact of the economic processes on the cities: they have a strong impact on European cities since the early nineteenth century, but their impact on Italian cities (beginning from the main northern cities, Milan and Turin is more limited, if compared with the transformations concerning other continental cities.

    The unification starting from 1861 imposes additional critical elements, because the Italian urban structure is not ready to the event, particularly for the choice of the capital city. A city that can rightfully define itself as capital exists, and it is Turin; but it is peripheral to the rest of the Italian territory. Furthermore there is an in pectore capital city, Rome, that is the symbolic centre of the Italian history. But the city has to wait another ten years to join to the rest of Italy. The solution is to temporarily move the capitol to Florence, even if nobody explicitly says it to Florentines! The step from Turin to Florence, and from Florence to Rome sets in motion a complex organizational mechanism and a significant money‘s amount, invested in the effort to bring the two cities to the new role

A further set of measurable criteria sufficient to demonstrate EPR gedanken experiment is proposed, these being the set of criteria sufficient to demonstrate entanglement, by way of a measured violation of a necessary condition of separability. In this way, provided the spatial separation of systems is sufficient to ensur...

  14. Sustainable development, demography and sexual and reproductive health: inseparable linkages and their policy implications.

    Herrmann, Michael

    2014-05-01

    The greatest challenge today is to meet the needs of current and future generations, of a large and growing world population, without imposing catastrophic pressures on the natural environment. Meeting this challenge depends on decisive policy changes in three areas: more inclusive economic growth, greener economic growth, and population policies. This article focuses on efforts to address and harness demographic changes for sustainable development, which are largely outside the purview of the current debate. Efforts to this end must be based on the recognition that demographic changes are the cumulative result of individual choices and opportunities, and that demographic changes are best addressed through policies that enlarge these choices and opportunities, with a focus on ensuring unrestricted and universal access to sexual and reproductive health information and services, empowering women to fully participate in social, economic and political life, and investing in the education of the younger generation beyond the primary level. The article provides a strong argument for why the Programme of Action that was agreed at the International Conference on Population and Development (ICPD) 20 years ago continues to hold important implications and lessons for the formulation of the post-2015 development agenda, which is expected to supersede the Millennium Development Goals (MDGs).

  15. Cyclic Communication and the Inseparability of MIMO Multi-way Relay Channels

    KAUST Repository

    Chaaban, Anas; Sezgin, Aydin

    2015-01-01

    The K-user MIMO multi-way relay channel (Ychannel) consisting of K users with M antennas each and a common relay node with N antennas is studied in this paper. Each user wants to exchange messages with all the other users via the relay. A transmission strategy is proposed for this channel. The proposed strategy is based on two steps: channel diagonalization and cyclic communication. The channel diagonalization is applied by using zero-forcing beam-forming. After channel diagonalization, the channel is decomposed into parallel sub-channels. Cyclic communication is then applied, where signal-space alignment for network-coding is used over each sub-channel. The proposed strategy achieves the optimal DoF region of the channel if N M. To prove this, a new degrees-of-freedom outer bound is derived. As a by-product, we conclude that the MIMO Y-channel is not separable, i.e., independent coding on separate sub-channels is not enough, and one has to code jointly over several sub-channels.

  16. Endoscopia y sedación: un binomio inseparable para el gastroenterólogo

    Directory of Open Access Journals (Sweden)

    Javier Crespo

    Full Text Available RESUMEN El desarrollo de la endoscopia y su creciente demanda por la población han motivado un incremento en la necesidad de técnicas de sedación con propofol. Este beneficio es indiscutible, para paciente y endoscopista, pero se deben considerar algunos aspectos sobre quién y cómo debe hacerse, en torno a la seguridad y el gasto sanitario. El propofol en endoscopia es la primera opción para la European Society of Gastrointestinal Endoscopy por su rapidez y corta vida media y hay muchas referencias sobre su seguridad usándolo especialistas de Aparato Digestivo no anestesistas. En este mismo número de REED, hay varios originales que avalan la eficiencia y seguridad incluso en procedimientos complejos, de alto riesgo o largos como la colangiopancreatografía retrógrada endoscópica (CPRE o la enteroscopia. El propofol puede ser administrado con seguridad y eficacia por un equipo con competencias específicas adquiridas mediante un programa formativo y usando un procedimiento específico. Pero en la práctica real se presentan varias dificultades para dicha capacitación, que debe figurar en la formación del sistema MIR en España. La Comisión Nacional de Digestivo, sensible a esta laguna formativa, ha recogido en su nuevo programa MIR (en evaluación cuatro competencias, en concreto la 145: entrenamiento en sedación profunda. También la Sociedad Española de Endoscopia Digestiva (SEED ha hecho un esfuerzo formativo importante, con más de 50 cursos de sedación dirigidos a endoscopistas y enfermeras. La formación o capacitación continuada en este campo (por ejemplo, la renovación de los cursos de reanimación cardiopulmonar avanzada debería ser un objetivo en todas las unidades de endoscopias. Dada la diversidad de nuestros hospitales, con salas de endoscopias únicas o múltiples, deben hacerse esfuerzos a nivel local para que los responsables de los servicios de Aparato Digestivo y Anestesiología establezcan los circuitos asistenciales necesarios para garantizar la seguridad del paciente, elaborando los protocolos que en cada caso sean precisos y debiendo llegar a un consenso entre las sociedades científicas implicadas (Sociedad Española de Patología Digestiva [SEPD], SEED y Sociedad Española de Anestesiología y Reanimación [SEDAR] y sus correspondientes comisiones nacionales.

    2016-02-01

    Full Text Available The article considers the issues of a personality’s self-realization and self-actualization under current educational standards required in the time of impetuous development in informative technologies. The practical aspect of the article describes self-realization and self-actualization of a person as their social and useful activity, interdiscipline approach, it is characterised by interdependence of an individual and their social environment apart with the self-realization of a personality in educational process. Evidently, being a substantial ca-tegory of vital «self-assertion», it should be thought over in categories of self-actualization and self-realization. So, self-realization is considered to be a social process which continues all conscientious life. In pedagogics of our country, labour and professional activity were the spheres of self-actualization therefore, it should be taken into account external factors for self-realization and self-actualization of a person. If socio-pedagogic conditions presuppose having good teachers, what conditions should be created in an individual’s micro-groups and in particular, in the family and kind of values shoud an individual get through the process of socialization. Thus, technological project of self-realization of a personality has to assume that there is the strive for self-perfection and interrelation of ways of self-realization, self-education, and adaptation. The correlation of these ways in a specific educational field is the purpose of the article.

  1. La formación de los médicos: un continuo inseparable

    2015-01-01

    Full Text Available Actualmente estamos sumergidos en un mundo en el cual su principal característica es el cambio constante. Por este motivo, es necesario que el médico sea competente a lo largo de toda su vida profesional. Los adultos aprenden de manera independiente de los profesores y de una forma que está íntimamente ligada a su experiencia. El aprendizaje a lo largo de toda la vida debe ser entendido como un término genérico que incluye e incorpora muchos aspectos o componentes del aprendizaje. Estos aspectos o componentes, cuando se toman juntos, forman un continuo. Este continuo puede verse como una serie o conjunto de actividades de aprendizajes específicos y complementarios, que pueden ser integradas por el médico en momentos diferentes para satisfacer distintos objetivos o prioridades. La motivación de los médicos para participar en el aprendizaje se basa en la necesidad de reducir la tensión creada por la diferencia que existe entre “lo que es” y “lo que debería ser”. Históricamente, la formación médica continuada se ha centrado en las actividades formales; sin embargo, hay muchas más actividades de aprendizaje en el proceso de aprendizaje continuo, tales como: el aprendizaje de adultos, el aprendizaje autodirigido, la reflexión y el aprendizaje en grupos. Todas estas actividades de aprendizaje pueden ayudar a estructurar tipos formales, semiformales e informales de los planes y programas de aprendizaje.

    High baseline autism spectrum disorder prevalence estimates in New Jersey led to a follow-up surveillance. The objectives were to determine autism spectrum disorder prevalence in the year 2006 in New Jersey and to identify changes in the prevalence of autism spectrum disorder or in the characteristics of the children with autism spectrum disorder, between 2002 and 2006. The cohorts included 30,570 children, born in 1998 and 28,936 children, born in 1994, residing in Hudson, Union, and Ocean counties, New Jersey. Point prevalence estimates by sex, ethnicity, autism spectrum disorder subtype, and previous autism spectrum disorder diagnosis were determined. For 2006, a total of 533 children with autism spectrum disorder were identified, consistent with prevalence of 17.4 per 1000 (95% confidence interval = 15.9-18.9), indicating a significant increase in the autism spectrum disorder prevalence (p autism spectrum disorder was broad, affecting major demographic groups and subtypes. Boys with autism spectrum disorder outnumbered girls by nearly 5:1. Autism spectrum disorder prevalence was higher among White children than children of other ethnicities. Additional studies are needed to specify the influence of better awareness of autism spectrum disorder prevalence estimates and to identify possible autism spectrum disorder risk factors. More resources are necessary to address the needs of individuals affected by autism spectrum disorder.

    Full Text Available Objective: the aim of this study was to identify the prevalence of constipation in diabetic patients treated at the endocrinology outpatient clinic at Hospital Universitário Professor Alberto Antunes and PAM Salgadinho, from April to August 2013. Methods: a descriptive and cross-sectional study, carried out through a questionnaire using the Rome III criteria in 372 patients treated at the outpatient endocrinology clinic. Results: of 372 patients evaluated, the frequency of constipation found was 31.2% among diabetic patients. Females predominated in the sample (72.8% as well as for the frequency of constipation (80.2%. The incidence of type II diabetes was 97.3% and it was observed that 80.2% of the sample was older than 50 years. One hundred and twelve patients with inadequate glycemic control (HgA1c ≥ 7 had an association with constipation. Conclusion: there was an increased frequency of constipation in patients with diabetes mellitus according to the Rome III criteria, in relation to the general population. The inadequate glycemic control in patients with diabetes mellitus increases the frequency of constipation and it is necessary to perform studies that allow the confirmation of this association to demonstrate this hypothesis.

    1999-06-01

    There are limited data available on the prevalence of stroke in the United Kingdom. Such data are important for the assessment of the health needs of the population. This study aimed to determine the prevalence of stroke and the prevalence of associated dependence in a district of northern England. This was a two-stage point prevalence study. A valid screening questionnaire was used to identify stroke survivors from an age- and sex-stratified sample of the population aged 45 years and over in a family health services authority district. This was followed by assessment of stroke patients with scales of disability and handicap. The overall prevalence of stroke was found to be 17.5/1000 (95 per cent confidence interval (CI) 17.0, 18.0). The prevalence of stroke-associated dependence was 11.7/1000 (95 per cent CI 11.3, 12.1). Self-reported comorbidity was most commonly due to circulatory and musculoskeletal disorders. The prevalence of stroke in this district is considerably higher than current guidelines and previous results suggest. Nevertheless, the result from this study combined with that from a previous study in another district in the United Kingdom should allow those interested in epidemiologically based health needs assessment to make reasonable estimates of the burden of stroke in their area.

    Full Text Available OBJECTIVES: To estimate prevalence of chronic conditions among patients seeing a general practitioner (GP, patients attending general practice at least once in a year, and the Australian population. DESIGN SETTING AND PARTICIPANTS: A sub-study of the BEACH (Bettering the Evaluation and Care of Health program, a continuous national study of general practice activity conducted between July 2008 and May 2009. Each of 290 GPs provided data for about 30 consecutive patients (total 8,707 indicating diagnosed chronic conditions, using their knowledge of the patient, patient self-report, and patient's health record. MAIN OUTCOME MEASURES: Estimates of prevalence of chronic conditions among patients surveyed, adjusted prevalence in patients who attended general practice at least once that year, and national population prevalence. RESULTS: Two-thirds (66.3% of patients surveyed had at least one chronic condition: most prevalent being hypertension (26.6%, hyperlipidaemia (18.5%, osteoarthritis (17.8%, depression (13.7%, gastro-oesophageal reflux disease (11.6%, asthma (9.5% and Type 2 diabetes (8.3%. For patients who attended general practice at least once, we estimated 58.8% had at least one chronic condition. After further adjustment we estimated 50.8% of the Australian population had at least one chronic condition: hypertension (17.4%, hyperlipidaemia (12.7%, osteoarthritis (11.1%, depression (10.5% and asthma (8.0% being most prevalent. CONCLUSIONS: This study used GPs to gather information from their knowledge, the patient, and health records, to provide prevalence estimates that overcome weaknesses of studies using patient self-report or health record audit alone. Our results facilitate examination of primary care resource use in management of chronic conditions and measurement of prevalence of multimorbidity in Australia.

    2005-01-01

    To present the prevalence of depressive episodes, as well as the percentage of the population with medical diagnosis. The definition of depression was based on a schedule with DSM IV diagnostic criteria. Using data from the 2002-2003 National Assessment Performance Survey, the prevalence of depression was estimated at the national level, by sex, age, education, size of residence community, and state. The percentage of individuals with medically diagnosed depression and the percentage of those under treatment were also estimated. The national prevalence of depression was 4.5%: 5.8% in women and 2.5% in men. The prevalence of depression increased with age and decreased with higher education. Among males, the prevalence was higher in rural than urban communities. A large percentage of affected individuals have no medical diagnosis. Depression is a frequent disease in adults.A higher prevalence is associated with social vulnerability. The low percentage of diagnosis represents a challenge for mental health service planning and provision.

    In the 70's a pilot plant for studies of different concentrates processing obtained from the chemical processing of monazite was operated at IPEN / CNEN-SP, with a view to obtaining thorium of nuclear purity. This unity was operated on an industrial scale since 1985, generating around 25 metric tons of residue and was closed in 2002. This waste containing thorium and rare earths was named Retoter (Rejeito de Torio e Terras Raras, in portuguese) and stored in the IPEN Safeguards shed. This paper studies the treatment of the waste, aimed at environmental, radiological and technology. Were studied two cases for the chromatographic separation of thorium from rare earths. One of them was the chromatographic extraction, where the extracting agent tributyl phosphate was supported on polymeric resins Amberlite XAD16. The other method is studied for comparison purposes, since the material used in chromatographic extraction is unprecedented with regard to the separation of thorium, was the ion-exchange chromatography using DOWEX 1-X8 strong cationic resin. Was studied also the chromatographic process of extraction with the extracting agent DEHPA supported on Amberlite XAD16 for the fractionation in groups of rare earths elements. Thorium was separated with high purity for strategic purposes and rare earths recovered free from thorium, were tested as a catalyst for ethanol reforming to hydrogen obtaining which is used in fuel cells for power generation.

    Full Text Available Introduction: Hypertension in pregnancy is one of the three factors of maternal mortality. Etiology of the disease is unknown, but the many factors contributing to the identification and control of it can be taken a step to prevent and reduce the symptoms of the disease. The purpose of this study was to determine the prevalence of preeclampsia (high-blood pressure in different seasons of the year. Methods: The present retrospective cross-sectional study was conducted on more than 8,000 pregnant women visiting Assali specialized hospital from 2011 to 2013. Required data was collected through questionnaire checklist. The Chi-square test with multiple comparisons was used to compare the frequencies of pregnancy-induced hypertension (PIH according to the month of year, and adjustment of multiplicity was conducted using Bonferroni's method. Student's t-test was used to compare the means of PIH prevalence rates. In all analyses, P < 0.05 was taken to indicate statistical significance. Results: In these 8000 woman admitted to labor, overall prevalence of PIH was 3.8 ± 0.6%. The prevalence rate of PIH was highest in the summer (4.5% and lowest frequent in the winter (2.7%, respectively. In July, the prevalence rate was significantly higher than those for any other month (4.7%, and in March, it was lower prevalence than for any month (2.2%, respectively. Using the Chi-square test, a significant difference between the incidence of disease was observed in summer and winter (P < 0.001. Conclusion: The prevalence rate of PIH was higher for delivery in summer and early spring and lowest for winter delivery among Khorramabad women based on these results; it seems that changes in temperature and humidity in different seasons can affect preeclampsia, and preeclampsia increases with increasing frequency temperature.

    Oppositional defiant disorder (ODD) is characterized by a pattern of negative, defiant, disobedient and hostile behavior toward authority figures. ODD is one of the most frequent reasons for clinical consultation on mental health during childhood and adolescence. ODD has a high morbidity and dysfunction, and has important implications for the future if not treated early. To determine the prevalence of ODD in schoolchildren aged 6-16 years in Castile and Leon (Spain). Population study with a stratified multistage sample, and a proportional cluster design. Sample analyzed: 1,049. Cases were defined according to DSM-IV criteria. An overall prevalence rate of 5.6% was found (95% CI: 4.2%-7%). Male gender prevalence=6.8%; female=4.3%. Prevalence in secondary education=6.2%; primary education=5.3%. No significant differences by gender, age, grade, type of school, or demographic area were found. ODD prevalence without considering functional impairment, such as is performed in some research, would increase the prevalence to 7.4%. ODD cases have significantly worse academic outcomes (overall academic performance, reading, maths and writing), and worse classroom behavior (relationship with peers, respect for rules, organizational skills, academic tasks, and disruption of the class). Castile and Leon has a prevalence rate of ODD slightly higher to that observed in international publications. Depending on the distribution by age, morbidity and clinical dysfunctional impact, an early diagnosis and a preventive intervention are required for health planning. Copyright © 2013 SEP y SEPB.

    Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. 1519 (36.7%) patients had at least one dental anomaly. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other anomalies were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). The most prevalent anomaly in the Indian population was congenitally missing teeth (16.3%), and the second frequent anomaly was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent anomalies, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these anomalies may be low, the early diagnosis is imperative for the patient management and treatment planning. Key words:Dental anomaly, prevalence, panoramic radiography.

Method: In this cross-sectional population-based epidemiological study (age > 18 in Iran, 25180 individuals were selected through a randomized cluster sampling method for a diagnosis using the Schedule for Affective Disorders and Schizophrenia (SADS. They were then interviewed at home by 250 trained clinical psychologists. Results: The estimated lifetime prevalence of Major Depressive Disorder (MDD and Minor Depressive Disorder (mDD were 3.1% and 0.3% respectively. Also, the estimated lifetime prevalence of Bipolar Mood disorder (BMD type I and type II were 0.1% and 0.7% respectively. The current prevalence of MDD, mDD, BMD-I, and BMD-II were 1.8%, 0.2%, 0.04%, and 0.3% respectively. Mood disorders were associated with female gender, lower education, being married, being middle-aged, living in cities, and not being a homemaker. Conclusion: The prevalence of mood disorders was lower among Iranian adults than reported in Western studies, and a number of demographic associations differed from those reported in Western studies. Important cultural differences in the nature or manifestation of depression are implied by these results.

    To evaluate the published medical literature on the prevalence and types of food allergies in South Asia. A PubMed search was performed using the keywords India and food allergy, Asia and food allergy, and South Asia and food allergy for any period. Articles cited in selected studies were reviewed for their appropriateness of inclusion into this review. Publications were included that were original research and fit the topic of food allergy and South Asia. South Asia is defined as region inclusive of India, Pakistan, Bangladesh, and Sri Lanka. A total of 169 articles were initially identified, and 47 were reviewed in detail for inclusion in this review. The primary focus was placed on 10 studies that consisted of case reports of newly reported or documented food allergy, survey studies that investigated food allergy prevalence in specific demographics, and prospective and cross-sectional studies with case controls, all of which investigated food allergy prevalence by allergy testing in a selected population. The medical literature on the prevalence and types of food allergy in South Asia indicates that there is a variety of unusual and unique allergens and an overall low incidence of food allergy. There is also an association of increased food allergy prevalence in individuals who live in metropolitan regions or who migrate to communities that have adopted westernization.

    Full Text Available Obesity is a major public health problem affecting an important proportion of the Turkish population. The prevalence of obesity has significantly increased among adult Turkish population over the past 20 years. In 1990, 18.8% of the adult population was obese (28.5% among women and 9% among men, and the prevalence increased to 36% in 2010 (44% among women and 27% among men. From the data, we found that the prevalence of obesity in Turkey has increased steadily from 1990 to 2010 in both genders. Adult obesity-associated risk factors are age, gender, hypertension, hyperlipidemia, smoking cessation, alcohol consumption, high household income, low education level and physical activity, occupation, marital status and a family of selected medical conditions (e.g. obesity, diabetes and hypertension. To control obesity, necessary precautions should urgently be taken. The precautions include serious public health education encouraging a well-balanced diet and increasing physical activity.

    Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk. Recent studies concerning physician burnout treat specialists such as radiologists as one group. We studied burnout in musculoskeletal (MSK) subspecialist radiologists. An institutional review board exemption was obtained. Society of Skeletal Radiology members received invitations to an anonymous survey that included questions from the Maslach Burnout Inventory trademark (MBI) measuring all three aspects of burnout. The response rate was 36.4% (433/1190). The prevalence of emotional exhaustion was 61.7% (255/413), of depersonalization 53.3% (219/411), and of perceived lack of personal accomplishment 39.6% (161/407). Only 19.5% (79/405) of MSK radiologists reported no burnout, while 80.5% (326/405) reported burnout along one or more dimensions. For all three dimensions, the prevalence was higher and the mean severity was worse for private practice compared with academic practice. The prevalence of burnout was affected more by practice setting than by gender. Burnout prevalence and severity also varied systematically with years since completion of training. Among MSK radiologists, we found a much higher prevalence and greater severity of burnout than has been previously reported for radiologists and other physicians. There were differences in prevalence and severity of burnout among practice settings, genders, and longevity cohorts. (orig.)

    BACKGROUND Over the past 10 years, there has been a significant increase in the use of assisted reproductive technologies in Canada, however, little is known about the overall prevalence of infertility in the population. The purpose of the present study was to estimate the prevalence of current infertility in Canada according to three definitions of the risk of conception. METHODS Data from the infertility component of the 2009–2010 Canadian Community Health Survey were analyzed for married and common-law couples with a female partner aged 18–44. The three definitions of the risk of conception were derived sequentially starting with birth control use in the previous 12 months, adding reported sexual intercourse in the previous 12 months, then pregnancy intent. Prevalence and odds ratios of current infertility were estimated by selected characteristics. RESULTS Estimates of the prevalence of current infertility ranged from 11.5% (95% CI 10.2, 12.9) to 15.7% (95% CI 14.2, 17.4). Each estimate represented an increase in current infertility prevalence in Canada when compared with previous national estimates. Couples with lower parity (0 or 1 child) had significantly higher odds of experiencing current infertility when the female partner was aged 35–44 years versus 18–34 years. Lower odds of experiencing current infertility were observed for multiparous couples regardless of age group of the female partner, when compared with nulliparous couples. CONCLUSIONS The present study suggests that the prevalence of current infertility has increased since the last time it was measured in Canada, and is associated with the age of the female partner and parity.

    Full Text Available 對於以「德行教學」界定品格教育的常見質疑是:品格教育不過是被L.Kohlberg戲稱為「美德袋取徑」的翻版而已。為了消除這項疑慮,必須闡明各德行之間的關係。此論題過去是在具爭議性的「德行一體說」中被探討的。在為一種可信度較高的德行一體說辯護後,筆者歸結出該學說對於當前品格教育的重要啟示,包括:一、既然德行之間的整合是德行教學中必不可少的重要環節,則以分隔化的方式來教導各個德行是有問題的,尚須教導學生處理道德要求多於一種的複雜的道德情境;二、道德氣質的培養以及各德行所需的(評價性)知識的學習,乃是德行涵養的兩個主要任務;最後,「道德人格的多樣化」獲得該學說的支持,亦即,有德的人實際上是各具特色、多樣類型的,「道德品格的個殊化」這項重要議題也因而獲得彰顯。 A doubt often cast on the common practice of defining character education in terms of the inculcation of virtues is that it is simply a duplication of the “bag of virtues” approach, as derogatorily dubbed by L. Kohlberg. To dispel this misgiving, it is imperative to expound the relationship between the virtues, which was addressed in the controversial doctrine of the unity of the virtues in the past. After the author argue for a more plausible interpretation of it, some implications for character education are drawn in this study. Firstly, since the integration of the virtues is integral to the inculcation of virtues, it is problematic to teach the virtues in a compartmentalized way. Instead, it is necessary to learn how to confront a complex moral situation where more than one moral requirement is (are demanded of the moral agent. Secondly, it is made explicit that the cultivation of moral dispositions and the learning of (evaluative knowledge requisite for the various virtues are the two

    Not only“moral issues”,but also economic issues which involve complex business,interests,and society could be the obj ect of moral governance.Based on the theories of business ethics,it is incorrect to separate morality and economy,and try to govern moral issues j ust by moral methods.This misinformation is rooted in splitting understanding of economy and ethics.Because of the natural unity of economical and ethical phenomenon,moral governance should concern both economic and moral approach,and change the subj ect,obj ect and method of the governance accordingly.%道德治理的对象并非仅是纯粹的“道德问题”,同时也是源自经济生活、体现复杂经济关系、利益关系和社会关系的经济问题。从经济伦理的视域考察,将道德治理的对象理解为与经济相分离的纯粹的“道德问题”,并进而试图以单一的道德手段加以治理,这种认识误区的理论根源在于对经济与伦理的分割式理解。秉持经济与伦理内在统一的基本立场,道德治理也应实现从“道德”治理走向“经济-伦理”治理的范式转换,从而在内容、主体和方法上进行相应的转变。

    All-inorganic perovskites have emerged as a new class of phosphor materials owing to their outstanding optical properties. Zero-dimensional inorganic perovskites, in particular the Cs4PbBr6-related systems, are inspiring intensive research owing to the high photoluminescence quantum yield (PLQY) and good stability. However, synthesizing such perovskites with high PLQYs through an enviromentally friendly, cost-effective, scalable, and high-yield approach remains challenging, and their luminescence mechanisms has been elusive. Here, we report a simple, scalable, room-temperature self-assembly strategy for the synthesis of Cs4PbBr6/CsPbBr3 perovskite composites with near-unity PLQY (95%), high product yield (71%) and good stability, using low-cost, low-toxicity chemicals as precursors. A broad range of experimental and theoretical characterizations suggest that the high-efficiency PL originates from CsPbBr3 nanocrystals well passivated by the zero-dimensional Cs4PbBr6 matrix that forms based on a dissolution-crystallization process. These findings underscore the importance in accurately identifying the phase purity of zero-dimensional perovskites by synchrotron X-ray technique to gain deep insights into the structure-property relationship. Additionally, we demonstrate that green-emitting Cs4PbBr6/CsPbBr3, combined with red-emitting K2SiF6:Mn4+, can be used for the construction of WLEDs. Our work may pave the way for the use of such composite perovskites as highly luminescent emitters in various applications such as lighting, displays, and other optoelectronic and photonic devices.

    2017-10-01

    Full Text Available Published data on the prevalence of autism spectrum disorders point to a significant increase in this indicator. This increase is being studied in numerous publications of analysis, meta-analysis and systematic reviews. The prevalence indicates the proportion of people who suffer at a given time or are diagnosed with a disease. The consequences of the increasing prevalence are relevant from the point of health, social and educational, but especially relevant when as is the case, the cause of the disorder is unknown. It is in this sense that the prevalence study gains importance in order to delimit various circumstances that may give clues to the possible cause or causes that generate disorder. This article reviews studies, summarizes the last data, and reflects on them and possible causes that justify the increased reporting. It looks like these epidemiological indicators can or are influenced by possible methodological flaws behind, which can explain the variations between studies and others. It concludes by stating the need population studies and monitoring that allows us to know the reality of the evolution of these disorders in order to provide reliable information to those responsible for the institutions involved in the detection and treatment of ASD.

    2007-01-01

    Objective was to determine the prevalence of osteoporosis in healthy Saudi men. We randomly recruited 429 Saudi men from the community. The recruited Saudi men were subjected to an interview to reveal their lifestyle parameters, calcium intake and level of activity. Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)

    Full Text Available Research Question: What is the sickness prevalence in the slums of a metropolitan city? Objectives: To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi. Study Design: A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected. Participants: Data were collected from 1049 households consisting of 5358 individuals′ information. Results: The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers. Conclusion: From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.

  7. Prevalence & consequences of anaemia in pregnancy.

    Science.gov (United States)

    Kalaivani, K

    2009-11-01

    Prevalence of anaemia in India is among the highest in the world. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50 per cent of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake due to low vegetable consumption, perhaps low B12 intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. In India, anaemia is directly or indirectly responsible for 40 per cent of maternal deaths. There is 8 to 10-fold increase in MMR when the Hb falls below 5 g/dl. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. A doubling of low birth weight rate and 2 to 3 fold increase in the perinatal mortality rates is seen when the Hb is anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in pregnancy can lead to substantial reduction in undernutrition in childhood, adolescence and improvement in adult height.

    ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge. Intending to reduce the prevalence of tobacco use among young

    Periodontitis and type 2 diabetes mellitus are known to be associated. The relationship between periodontal microbiota and early diabetes risk has not been studied. We investigated the association between periodontal bacteria and prediabetes prevalence among diabetes-free adults. ORIGINS (the Oral Infections, Glucose Intolerance and Insulin Resistance Study) cross sectionally enrolled 300 diabetes-free adults aged 20 to 55 y (mean ± SD, 34 ± 10 y; 77% female). Prediabetes was defined as follows: 1) hemoglobin A1c values ranging from 5.7% to 6.4% or 2) fasting plasma glucose ranging from 100 to 125 mg/dL. In 1,188 subgingival plaque samples, 11 bacterial species were assessed at baseline, including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Actinomyces naeslundii. Full-mouth clinical periodontal examinations were performed, and participants were defined as having no/mild periodontitis vs. moderate/severe periodontitis per the definition of the Centers for Disease Control and Prevention / American Academy of Periodontology. Modified Poisson regression evaluated prediabetes prevalence across bacterial tertiles. Prevalence ratios and 95% confidence intervals for third vs. first tertiles are presented. All analyses were adjusted for cardiometabolic risk factors. All results presented currently arise from the baseline cross section. Prediabetes prevalence was 18%, and 58% of participants had moderate/severe periodontitis. Prevalence ratios (95% confidence intervals) summarizing associations between bacterial levels and prediabetes were as follows: A. actinomycetemcomitans, 2.48 (1.34, 4.58), P = 0.004; P. gingivalis, 3.41 (1.78, 6.58), P = 0.0003; T. denticola, 1.99 (0.992, 4.00), P = 0.052; T. forsythia, 1.95 (1.0, 3.84), P = 0.05; A. naeslundii, 0.46 (0.25, 0.85), P = 0.01.

    Full Text Available ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA, which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4 had smoked at least once in life, 5.7% (95%CI 5.3-6.2 smoked at the time of the research, and 2.5% (95%CI 2.2-2.8 smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

    To determine whether the high prevalence of reported asthma in Melbourne schoolchildren is seen in rural Victoria. A questionnaire on respiratory symptoms was distributed to children to be completed by parents and returned to the school. Results were compared with a previous Melbourne study. Two hundred and twenty-seven government and non-government primary schools in five rural regions of Victoria: coast, wheatbelt, riverland, highland and Latrobe valley. All children enrolled in grade 2 were invited to join the study. Parents completed questionnaires for 4661 children after 4886 questionnaires were distributed (response rate, 95%). History of wheeze in the past 12 months. The overall prevalence of wheeze in the last 12 months was 23.6%. There was a significant difference overall in this rate across the five rural areas and Melbourne, with the Latrobe Valley (26.2%) and highland areas (25.0%) having the highest rate, and the wheatbelt the lowest (19.6%). The spectrum of severity of asthma was similarly distributed across rural regions, although severe episodes were significantly more frequently reported by parents from rural areas than by parents in Melbourne. The reported use of bronchodilators and diagnosis of asthma showed a similar pattern of variation to that of the 12-month prevalence of wheeze. The prevalence of asthma in 7-year-old children is similar for rural Victoria as a whole compared with Melbourne, but there is variability in asthma prevalence in individual rural areas which is difficult to account for in terms of known environmental precipitants.

    Teen drivers' over-involvement in crashes has been attributed to a variety of factors, including distracted driving. With the rapid development of in-vehicle systems and portable electronic devices, the burden associated with distracted driving is expected to increase. The current study identifies predictors of secondary task engagement among teenage drivers and provides basis for interventions to reduce distracted driving behavior. We described the prevalence of secondary tasks by type and driving conditions and evaluated the associations between the prevalence of secondary task engagement, driving conditions, and selected psychosocial factors. The private vehicles of 83 newly-licensed teenage drivers were equipped with Data Acquisition Systems (DAS), which documented driving performance measures, including secondary task engagement and driving environment characteristics. Surveys administered at licensure provided psychosocial measures. Overall, teens engaged in a potentially distracting secondary task in 58% of sampled road clips. The most prevalent types of secondary tasks were interaction with a passenger, talking/singing (no passenger), external distraction, and texting/dialing the cell phone. Secondary task engagement was more prevalent among those with primary vehicle access and when driving alone. Social norms, friends' risky driving behaviors, and parental limitations were significantly associated with secondary task prevalence. In contrast, environmental attributes, including lighting and road surface conditions, were not associated with teens' engagement in secondary tasks. Our findings indicated that teens engaged in secondary tasks frequently and poorly regulate their driving behavior relative to environmental conditions. Practical applications: Peer and parent influences on secondary task engagement provide valuable objectives for countermeasures to reduce distracted driving among teenage drivers.

    One of the most prevalent chronic diseases among elderly population is the Metabolic Syndrome (MetS). The aim of this study was to assess the prevalence of MetS and associated factors among Mexican elderly people. Cross-sectional survey carried out in Mexico (2007). A random sample (n=516) of the elderly population (≥65years; 277 female, 239 male) was interviewed. Anthropometric and analytical measurements, and a general questionnaire incorporating questions related to socio-demographic and life-style factors were used. MetS definition AHA/NHLBI/IDF was applied. The prevalence of MetS in the elderly (≥65years) was of 72.9% (75.7% men; 70.4% women). Participants with values above MetS cut-off points were 92.4% (hypertension), 77.8% (hypertriglyceridemia), 77.1% (low HDL-cholesterol), 71.1% (hyperglycaemia), and 65.4% (central obesity). People with MetS showed higher values of anthropometric and biochemical variables than those without MetS, except for the height, cholesterol and creatinine. Mid-high education level (9-12 years), no smokers and former smokers, and Central-Western inhabitants of Mexico were associated with MetS components. BMI status was the main determinant of MetS prevalence and MetS components. The reported prevalence of MetS among the elderly Mexican population was higher than those previously obtained in the geographical area, showing a major public health problem in Mexican elders.

    Introduction Racial disparities in obesity exist at the individual and community levels. Retail food environment has been hypothesized to be associated with racial disparities in obesity prevalence. This study aimed to quantify how much food environment measures explain racial disparities in obesity at the county level. Methods Data from 2009 to 2010 on 3,135 U.S. counties were extracted from the U.S. Department of Agriculture Food Environment Atlas and the Behavioral Risk Factor Surveillance System and analyzed in 2013. Oaxaca–Blinder decomposition was used to quantify the portion of the gap in adult obesity prevalence observed between counties with a high and low proportion of African American residents is explained by food environment measures (e.g., proximity to grocery stores, per capita fast food restaurants). Counties were considered to have a high African American population if the percentage of African American residents was >13.1%, which represents the 2010 U.S. Census national estimate of percentage African American citizens. Results There were 665 counties (21%) classified as a high African American county. The total gap in mean adult obesity prevalence between high and low African American counties was found to be 3.35 percentage points (32.98% vs 29.63%). Retail food environment measures explained 13.81% of the gap in mean age-adjusted adult obesity prevalence. Conclusions Retail food environment explains a proportion of the gap in adult obesity prevalence observed between counties with a high proportion of African American residents and counties with a low proportion of African American residents.

    Central nervous system dysfunction, such as hyperexcitation, irritability, and disturbance of consciousness, may occur in patients with thyrotoxicosis. There are also a few case reports of seizures attributed to thyrotoxicosis. The objective of the present study was to determine the prevalence of seizures that appeared to be related to the thyrotoxic state in patients with thyrotoxicosis. We retrospectively determined the prevalence and clinical features of seizures in 3382 patients with hyperthyroidism. Among patients with seizures, we excluded those with other causes of seizures or a history of epilepsy. We did not exclude two patients in whom later work-up showed an abnormal magnetic resonance imaging, as their seizures resolved after they became euthyroid. Among the 3382 patients with hyperthyroidism, there were seven patients (0.2%) with seizures who met our criteria. Primary generalized tonic-clonic seizures occurred in four patients (57%), complex partial seizures with secondary generalized tonic-clonic seizures occurred in two patients (29%), and one patient had a focal seizure (14%). The initial electroencephalography (EEG) was normal in two patients (29%), had generalized slow activity in four patients (57%), and had diffuse generalized beta activity in one patient (14%). On magnetic resonance imaging, one patient had diffuse brain atrophy, and one had an old basal ganglia infarct. After the patients became euthyroid, the EEG was repeated and was normal in all patients. During follow-up periods ranging from 18 to 24 months, none of the patients had seizures. Hyperthyroidism is the precipitating cause of seizures in a small percentage of these patients. In these patients, the prognosis is good if they become euthyroid. The prevalence of thyrotoxicosis-related seizures reported here can be used in conjunction with the prevalence of thyrotoxicosis in the population to estimate the prevalence of thyrotoxicosis-related seizures in populations.

    The paper has the goal to analyse the correlation of the flexibility of all organizational functions. Based upon theoretical and practical studies, the decrease of flexibility into an "activity area" of organizations implies a diminution on a large scale of the flexibility of the processing system as a law expression of the decreasing outputs within economy. Therefore, at the level of each organizational function there are several major directions ensuring the flexibility of the "ensemble".

    Developments in elementary particle physics and astrophysics as well as cosmology, together with the introduction of new concepts and paradigms, are opening up new possibilities to achieve a synthesis of the infinitesimally small and the infinitesimally large. This synthesis will have a great impact not only on specific fields of science, but will change the entire concept of the world. Elementary particle physics is in the process of abandoning Democritus' philosophy of indivisible atoms and approaching the Platonic concept of symmetry. Investigating the composition of matter also involves the question about what happened before the Big Bang, and whether there was any Big Bang as a singular event. (orig.) [de

    In recent years there has been a resurgence of interest in the law of public international organizations. This fifth, revised edition of International Institutional Law covers the most recent developments in the field. Although public international organizations such as the United Nations, the World Trade Organization, the World Health Organization, ASEAN, the European Union and other organizations have broadly divergent objectives, powers, fields of activity and numbers of member states, they also share a wide variety of institutional problems. Rather than being a handbook for specific organizations, the book offers a comparative analysis of the institutional law of international organizations. It includes comparative chapters on the rules and practices concerning membership, institutional structure, decision-making, financing, legal order, supervision and sanctions, legal status and external relations.

    Full Text Available In the present article author was investigated questions about subject and a concept of aesthetic in the constellation of a modern philosophy. The question is prepared on a historical view of matter, and in the bordering line of a sense of a essence of things. As a matter of a sense of substance we must have a hermeneutical preparing in a historical dimension, what it is, and after that make a judgment what is not possible to be. Investigations always take us back to the antique period of philosophical researches because there is substance considering without any commas dealing with a strange interests looking from the side of pure philosophy. Beauty, good and a truth still must be a comprehensive values or a super transcendental beings in the sort of lights of a thinking. Thinking is possible if we have adequate ideas on the mind, and that ideas must have a spiritual space for them existing in us, or in the continuing of a life of the history of philosophy as a matter of our aesthetical meanings and a habit of the spirit. By that sign in our awareness mind we take out duty to building self-consciousness, as a personal updating and also take to philosophy that what she asks from us today.

The verses pertain to the Masha ritual enacted annually in Mangas, central Peru, and combine Quechua (the indigenous language with Spanish. Through detailed exegesis of the texts, this essay argues that, far from being irreconcilable, “unity” and “difference” are best understood as mutually informing since the recognition of difference opens up the parameters of potential exchange. This optic is informed by a worldview that emphasizes “relation” over “entities.”

    We aimed to estimate the prevalence of refractory hypertension (RfH) and to determine the clinical differences between these patients and resistant hypertensives (RH). Secondly, we assessed the prevalence of white-coat RfH and clinical differences between true- and white-coat RfH patients. The present analysis was conducted on the Spanish Ambulatory Blood Pressure Monitoring Registry database containing 70 997 treated hypertensive patients. RH and RfH were defined by the presence of elevated office blood pressure (≥140 and/or 90 mm Hg) in patients treated with at least 3 (RH) and 5 (RfH) antihypertensive drugs. White-coat RfH was defined by RfH with normal (<130/80 mm Hg) 24-hour blood pressure. A total of 11.972 (16.9%) patients fulfilled the standard criteria of RH, and 955 (1.4%) were considered as having RfH. Compared with RH patients, those with RfH were younger, more frequently male, and after adjusting for age and sex, had increased prevalence of target organ damage, and previous cardiovascular disease. The prevalence of white coat RfH was lower than white-coat RH (26.7% versus 37.1%, P <0.001). White-coat RfH, in comparison with those with true RfH, showed a lower prevalence of both left ventricular hypertrophy (22% versus 29.7%; P =0.018) and microalbuminuria (28.3% versus 42.9%; P =0.047). The prevalence of RfH was low and these patients had a greater cardiovascular risk profile compared with RH. One out of 4 patients with RfH have normal 24-hour blood pressure and less target organ damage, thus indicating the important role of ambulatory blood pressure monitoring in guiding antihypertensive therapy in difficult-to-treat patients. © 2017 The Authors.

    This study aims at determining the prevalence of neonatal hypoglycemia and its underlying causes. In this prospective study 14168 newborns delivered in Tabriz Alzahra Hospital during 2 years were evaluated in regard to blood glucose level at first 24 h of life. Glucose oxidase method with 4-aminophenazone with a Greiner G-300 was the used method for determining the blood glucose level. Cases with blood glucose causes of this condition, as well as the short-term mortality rate were determined. Prevalence of neonatal hypoglycemia was 0.4% (52 newborns). Underlying causes of hypoglycemia were prematurity (61.5%), diabetic mother (13.6%), septicemia (9.6%), perinatal asphyxia (9.6%), stress (3.8%) and neonatal hyperinsulinism (1.9%). The mortality rate was 53.8%, with prematurity as the leading cause of death.

    The authors classified 1,760 heterosexual pornographic magazines according to the imagery of the cover photographs. Covers depicting only a woman posed alone predominated in 1970 but constituted only 10.7% of the covers in 1981. Bondage and domination imagery was the most prevalent nonormative imagery and was featured in 17.2% of the magazines. Smaller proportions of material were devoted to group sexual activity (9.8%), tranvestism and transsexualism (4.4%), and other nonnormative imagery. The authors suggest that pornographic imagery is an unobtrusive measure of the relative prevalence of those paraphilias associated with preferences for specific types of visual imagery and for which better data are lacking.

    To verify prevalence of falls and fear of falling, and to compare functional fitness among elderly women fallers and non-fallers. Seventy-eight elderly women participated in this study. Cases of falls and the fear of falling were self-reported by the elderly women, while the functional fitness was measured by a set of functional tests. Mean and standard deviation were used to describe the sample. Independent t-test was used to compare functional fitness between groups. The prevalence of falls in this sample was 32.4%. Among women fallers, 40% self-reported a high fear of falling. It is recommended that functional and resistance exercises are included in the preventive strategies for reducing risk factors for falls and its determinants in elderly women.

    Domestic violence is an extremely underreported crime and a growing social problem in the United States. However, the true burden of the problem remains unknown. To assess the reported prevalence of domestic violence among trauma patients. A 6-year (2007-2012) retrospective analysis of the prospectively maintained National Trauma Data Bank. Trauma patients who experienced domestic violence and who presented to trauma centers participating in the National Trauma Data Bank were identified using International Classification of Diseases, Ninth Revision diagnosis codes (995.80-995.85, 995.50, 995.52-995.55, and 995.59) and E codes (E967.0-E967.9). Patients were stratified by age into 3 groups: children (≤18 years), adults (19-54 years), and elderly patients (≥55 years). Trend analysis was performed on April 10, 2014, to assess the reported prevalence of domestic violence over the years. Trauma patients presenting to trauma centers participating in the National Trauma Data Bank. To assess the reported prevalence of domestic violence among trauma patients. A total of 16 575 trauma patients who experienced domestic violence were included. Of these trauma patients, 10 224 (61.7%) were children, 5503 (33.2%) were adults, and 848 (5.1%) were elderly patients. The mean (SD) age was 15.9 (20.6), the mean (SD) Injury Severity Score was 10.9 (9.6), and 8397 (50.7%) were male patients. Head injuries (46.8% of patients) and extremity fractures (31.2% of patients) were the most common injuries. A total of 12 515 patients (75.1%) were discharged home, and the overall mortality rate was 5.9% (n = 980). The overall reported prevalence of domestic violence among trauma patients was 5.7 cases per 1000 trauma center discharges. The prevalence of domestic violence increased among children (14.0 cases per 1000 trauma center discharges in 2007 to 18.5 case per 1000 trauma center discharges in 2012; P = .001) and adults (3.2 cases per 1000 discharges in 2007 to 4.5 cases per

    2010-01-01

    Full Text Available Purpose: This retrospective study was performed to determine the prevalence of lower extremity venous duplication using duplex ultrasound in the patient population of a large urban medical center. Materials and Methods: The reports of all lower extremity venous ultrasound examinations performed at our institution between January 1, 2002 and December 31, 2002 were reviewed. Ultrasound examinations that were performed for purposes other than the detection of lower extremity deep vein thrombosis were excluded. The prevalence of duplication and its specific location were recorded. In addition, the prevalence of thrombus and its specific location were also recorded. Results: A total of 3118 exams were performed in 2664 patients. Of the 2664 patients, 2311 had only one examination performed during the study period; 353 patients had more than one examination performed. We found that 10.1% of patients (270/2664 had at least one venous segment duplicated and 5.4% of patients (143/2664 had a thrombus in at least one venous segment. There was a statistically significant difference in the prevalence of both duplication and thrombus with a change in venous segment. Only 0.4% of patients (11/2664 had thrombus within a duplicated segment. Of those who had more than one examination performed, 15.3% (54/353 had the same venous segment(s seen on one examination but not another. Conclusion: Lower extremity venous duplication is a frequent anatomic variant that is seen in 10.1% of patients, but it may not be as common as is generally believed. It can result in a false negative result for deep vein thrombosis.

    Full Text Available The results of the regional studies on the frequency of Parkinson's disease (PD and the incidence of it in Russia have been generalized, the main factors that determine the quality of the estimates of this disease epidemiological indicators have been identifyd. The article summarizes data from 19 original studies on the epidemiology of parkinsonism and Parkinson's disease in Russia published between 2005-2015. Due to the statistical heterogeneity of the primary results computational analytics was not applied to the data; however, data consolidation allowed to perform a trend analysis of epidemiological indicators. The methodological basis of the majority of studies was medical aid appealabil-ity; two of the studies used door-to-door surveys. One of the studies returned questionably low epidemiological indicators obtained from the medical records, and the rest showed the standardized prevalence of 30.0-139.9/100,000 and incidence of 7.63-21.8/100,000 per year. Contribution of Parkinson's disease to the nosological structure of parkinsonism was >61.3%. Estimate of the number of patients with PD in Russia is approximately 210,000 people. Conclusions are made regarding the prevalence of PD in Russia according to the cross-cutting research on the level of indicators in the Western countries. The prevalence of PD by appealability is 2-3 times less than the prevalence in continuous research, both national and foreign. The incidence of PD, demonstrated in half of the studies, is stable from region to region and is comparable with the universally recognized values.

    To validate the estimates of the prevalence of multimorbidity based on administrative hospital discharge data, with medical records and chart reviews as benchmarks. Retrospective cohort study. Medical division of a tertiary care teaching hospital. A total of 170 medical inpatients admitted from the emergency unit in January 2009. The prevalence of multimorbidity for three different definitions (≥2 diagnoses, ≥2 diagnoses from different ICD-10 chapters, and ≥2 medical conditions as defined by Charlson/Deyo) and three different data sources (administrative data, chart reviews, and medical records). The prevalence of multimorbidity in medical inpatients derived from administrative data, chart reviews and medical records was very high and concurred for the different definitions of multimorbidity (≥2 diagnoses: 96.5%, 95.3%, and 92.9% [p = 0.32], ≥2 diagnoses from different ICD-10 chapters: 86.5%, 90.0%, and 85.9% [p = 0.46], and ≥2 medical conditions as defined by Charlson/Deyo: 48.2%, 50.0%, and 46.5% [p = 0.81]). The agreement of rating of multimorbidity for administrative data and chart reviews and administrative data and medical records was 94.1% and 93.0% (kappa statistics 0.47) for ≥2 diagnoses; 86.0% and 86.5% (kappa statistics 0.52) for ≥2 diagnoses from different ICD-10 chapters; and 82.9% and 85.3% (kappa statistics 0.69) for ≥2 medical conditions as defined by Charlson/Deyo. Estimates of the prevalence of multimorbidity in medical inpatients based on administrative data, chart reviews and medical records were very high and congruent for the different definitions of multimorbidity. Agreement for rating multimorbidity based on the different data sources was moderate to good. Administrative hospital discharge data are a valid source for exploring the burden of multimorbidity in hospital settings.

    The study aimed to assess the prevalence and causes of corneal blindness in a rural northern Chinese population. Cross-sectional study. The cluster random sampling method was used to select the sample. This population-based study included 11 787 participants of all ages in rural Heilongjiang Province, China. These participants underwent a detailed interview and eye examination that included the measurement of visual acuity, slit-lamp biomicroscopy and direct ophthalmoscopy. An eye was considered to have corneal blindness if the visual acuity was blindness and low vision. Among the 10 384 people enrolled in the study, the prevalence of corneal blindness is 0.3% (95% confidence interval 0.2-0.4%). The leading cause was keratitis in childhood (40.0%), followed by ocular trauma (33.3%) and keratitis in adulthood (20.0%). Age and illiteracy were found to be associated with an increased prevalence of corneal blindness. Blindness because of corneal diseases in rural areas of Northern China is a significant public health problem that needs to be given more attention. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

    Full Text Available BACKGROUND: The prevalence of the metabolic syndrome (MS has significantly increased over the last few decades and has become a main health challenge worldwide. Prevalence of MS is quickly rising in developing countries due to changing lifestyle. It was considered worthwhile to study MS and its components in granite workers since granite factories are situated in and around Khammam area. Moreover, no studies of MS in granite workers have been reported in literature. OBJECTIVES: Aim of our study is to assess the prevalence of metabolic syndrome and its components in granite workers. MATERIALS AND METHODS: 210 male workers in the age group of 20 - 50 working in granite industries located in and around the Khammam town of Telangana State are selected for the present study. Blood pressures (BP, waist circumference (WC were measured. Fasting blood samples were collected for the estimation of glucose and lipids. RESULTS: 69 subjects out of 210 were identified as having MS based on updated National cholesterol education programme - Adult Treatment Panel III (NCEP - ATP III guidelines. CONCLUSION: MS should be identified and remedial measures may be suggested, so that the risk of hypertension, cardiovascular risk, diabetes and the resultant morbidity is minimized and can be delayed

    Australia records the highest incidence of skin cancer in the world. In response to this, public education campaigns have incorporated messages about reducing sun exposure and avoiding sunburn. This study sought to describe the prevalence of and factors associated with sunburn in Queensland residents. The Queensland Cancer Risk Study was a population-based, cross-sectional survey of 9,298 respondents conducted via computer-assisted telephone interview during 2004. Sunburn prevalence and its association with socio-demographics and skin cancer risk variables were examined. More than two-thirds (70.4%) of respondents reported at least one episode of sunburn in the past 12 months, and one in 10 respondents reported at least one episode of severe sunburn in the past 12 months. Experiences of sunburn on two or more occasions were reported more frequently by males than females (57.6% versus 46.5%, psunburn were strongly associated with being male (OR=2.20 95%CI 1.84-2.63) and being aged 20 to 39 years compared to 60 to 75 years (OR=9.79, 95%CI=7.66-12.50). Sunburn remains highly prevalent among Queensland residents particularly among men and in the younger age groups.

    1990-01-01

    Controversy exists about the lumbosacral transitional vertebrae(LSTV) causing low back pain and lumbar disk abnormalities such as herniated nucleus pulposus(HNP), early disk degeneration or annulus bulging. The prevalence of the lumbosacral transitional vertebrae were evaluated. The classification of LSTV is presented based upon the radiomorphological changes of transverse process of the last presacral vertebra. The type I is dysplastic transverse process, type II is incomplete lumbarization/ sacralization, type III is complete lumbarization/ sacralization, and type IV is mixed is mixed (type II and type III). Simple radiographic findings of (804 patients including) 300 patients without low back pain. 400 patients with low back pain and 104 patients with disk abnormalities on CT scan have been analyzed. The prevalence of LSTV were 51.5% in normal control group, 40.8% in low back pain group and 46.2% in disk abnormality group. The type I is regarded as the forerunner of a true transitional vertebra and the prevalence of the true LSTB (type II, III, IV) were 11.6%, 18.3% and 13.5% on each groups. The type II and III in low back pain group and type II in disk abnormality group were relatively increased in incidence of LSTV than in normal control group. A patient with the type II or III of the LSTV may show low back pain more frequently than a patient without such a LSTV. The type II of LSTV may cause lumbar disk abnormalities more frequently

    Fatigue is an important symptom in general practice due to its association with physical, psychological and social problems. To determine the prevalence of fatigue as an unsolicited symptom during general practice consultations. A random sample of GPs practising in Ireland was invited to provide data on consultations held over one day. Data were recorded on the presence of fatigue as a main or supporting symptom, social and demographic characteristics. Data were recorded by 89 GPs on 1,428 consultations. The prevalence of fatigue was 25%. It was the main reason for attending the doctor in 6.5% and a secondary reason in 19%. Sixty-two per cent of patients were female and 48% were eligible for free GP services. The mean age was 47.1 years. The presence of fatigue was associated with: attending a female GP, being female, attending a GP who had been qualified for fewer years and attending the GP frequently. The prevalence of fatigue reported in this study is over three times higher than that reported in earlier work. Doctor characteristics appear to be as important as patient characteristics in determining fatigue.

    Full Text Available Os conflitos políticos e sociais dos últimos anos na Europa, como os com a imigração e o terrorismo, orientam muitas questões levantadas pelas ciências humanas na atualidade. No que se refere à medievalística, muitas obras e projetos europeus apresentam a discussão em torno da diversidade cultural européia, a qual pode ser fundamentada desde a Idade Média através do convívio e trocas culturais entre cristão, judeus e muçulmanos. No centro destas discussões, está a crítica à idéia de centro e periferia dentro da própria Europa e no mundo, além da reflexão sobre conceitos de europeização e africanização, utilizados pela historiografia européia desde a primeira metade do século XX até poucos anos atrás. Neste artigo, serão apresentadas, à luz da Nova História Cultural Alemã (Neue Kulturgeschichte, algumas críticas aos conceitos de europeização, africanização, centro, periferia e unidade cultural na Idade Média européia. Questões estas que acaloram os debates na Alemanha atual.Political and social conflicts during recent years in Europe - such as immigration and terrorism - have guided humanities issues today. Regarding Middle Age research, many works and projects present a debate on European cultural diversity, which lay the foundations since the Middle Ages through interaction and cultural exchanges between Christians, Jews and Muslims. Within the discussion, is the criticism to the idea of center and periphery within Europe itself and the world, as well as the consideration of concepts such as europeanization and africanization, used by European historiography, from the first half of the twentieth century until a few years ago. This article presents criticism to the concepts of europeanization, africanization, center, periphery, and cultural unity in the Middle Ages, in light of the New German Cultural History (Neue Kulturgeschichte, issues that inflame the debate in Germany today.

    Pathological gambling is a behavioral dependency on hazard games that is classified, in the DSM-IV, among impulse control disorders. According to many studies, the international prevalence of pathological ranges between 2 and 6%. This disorder is often accompanied by a considerable impact on patients' life as well as on the life of people surrounding them. Adolescents and young adults are considered to be a population at risk to develop this kind of behavioral dependency. The problem of pathological gambling is one of the major problems from which the Lebanese population of university students in Lebanese society suffers. The prevalence of pathological gambling in the Lebanese population of university students is lacking from the contemporary medical literature. In our study, five of the biggest private universities in Lebanon (Notre-Dame University of Louaizé [NDU], Lebanese American University [LAU], American University of Beirut [AUB], Saint-Joseph University [USJ] and Holy Spirit University of Kaslik [USEK]) were surveyed. Each questionnaire was based essentially on the South Oaks Gambling Screen (SOGS). Four hundred and seventy-seven questionnaires were completed in these universities. Among the 477 students that completed the questionnaire, 5.87% appeared to be suffering from pathological gambling; 25.15% of responding students presented some problems related to gambling while the rest of them, corresponding to 68.92%, had no problems related to gambling. This is the first study of its kind conducted in the Lebanon. Its interest lies in that it offers an important evaluation of the prevalence of pathological gambling in the Lebanese population of university students. According to this study, the prevalence of pathological gambling in Lebanese university students is high. Prevention programs and sensitization strategies are needed in order to prevent the occurrence of this disorder in the Lebanese young. More studies are needed in this domain in order to

But fortunately it is a preventable disease. Objective of this study was to analyse various epidemiological features of tuberculosis in District Kotli, a remote area of Northern Pakistan. This cross sectional study was conducted in District Kotli, Azad Kashmir from January to December 2009. Data was collected from eight national TB centres of District Kotli. It included all the diagnosed cases of tuberculosis, registered there during the study period. Various epidemiological aspects of these patients were analysed. Total number patients registered during the study period were 752. Of these 579 (76.99%) were pulmonary and 173 (23%) were extra-pulmonary tuberculosis (EPT). Total prevalence of tuberculosis was found to be 100.27 per 100,000. Prevalence of pulmonary TB was 77.2 while that of EPT was 23.07 per 100,000. There were 405 males (53.85%) and 347 females (46.14%). Most patients were 61-75 years of age (220, 29.25%). Overall 417 (55.44%) were 46-75 years. Housewives were affected most frequently (324, 43.08%). Labourers were also commonly involved (40.82%). All cause mortality was 29 (3.85%). Mortality due to tuberculosi as was 11 (1.04%). Among pulmonary tuberculosis, 259 (44.78%) were sputum smear positive and 320) (55.26%) were sputum smear negative. In EPT, most frequent was pleural effusion (74, 42%) and least frequent was skin involvement (3, 1.73%). Prevalence of tuberculosis in Kotli was lower than the overall prevalence in Pakistan. Male to female ratio was lower than that generally observed in Southeast Asia. It was more common in middle to old age population. Frequency was higher in housewives and labourers. Very significant proportion of pulmonary TB was sputum smear positive. Among EPT, pleural effusion was the most common mode of presentation.

    Background: Snacking has increased globally, but little is known about how Mexicans consume foods outside meals. Objective: The aim of this study was to examine the prevalence and patterns of snacking behavior among Mexicans. Methods: We used data from children and adults (aged ≥2 y; n = 9937) from the Mexican National Nutrition Survey 1999 and the Mexican National Health and Nutrition Survey (NHNS) 2012 to examine the prevalence of snacking as well as amount (kcal) and contribution of snacks to total energy intake per day. Snacking was defined as eating outside of the 3 main meals. We calculated per capita (among the total population) and per consumer (“snackers”) estimates of the number of snacks per day, kilocalories per snack, kilocalories per day from snacks, and the percentage of energy from snacks. Top foods consumed during snack occasions were also examined for the NHNS 2012. All results were weighted to account for survey design and to be nationally representative. Results: In 2012, an estimated 73% of the population consumed snacks on a given day, with estimates ranging from 70% among ≥59 y olds to 77% among 2–11 y olds. An average of 1.6 snacks/d were consumed by the population. This value was slightly higher (2.1 snacks/d) among snackers. Snacks provided an average of 343 kcal/d per snacker (17% of total energy/d). Fruit was the most commonly consumed snack food by all ages except for 12–18 y olds. Salty snacks, sweet snacks, sugar-sweetened beverages, and milk were frequently in the top 5 categories across age groups. Differences were observed between age groups. Conclusions: Snacking is prevalent in the Mexican population. Many, but not all, of the foods consumed during snack occasions are foods considered “foods to limit” in the United States.

    Full Text Available Abstract Background Footrot is a world-wide contagious disease in sheep and goats. It is an infection of the epidermis of the interdigital skin, and the germinal layers of the horn tissue of the feet. The first case of footrot in Swedish sheep was diagnosed in 2004. Due to difficulties in distinguishing benign footrot from early cases of virulent footrot and because there is no possibility for virulence testing of strains of Dichelobacter nodosus in Sweden, the diagnosis is based of the presence or absence of clinical signs of footrot in sheep flocks. Ever since the first diagnosed case the Swedish Animal Health Service has worked intensively to stop the spread of infection and control the disease at flock level. However, to continue this work effectively it is important to have knowledge about the distribution of the disease both nationally and regionally. Therefore, the aims of this study were to estimate the prevalence of footrot in Swedish lambs at abattoirs and to assess the geographical distribution of the disease. Methods A prevalence study on footrot in Swedish lambs was performed by visual examination of 2000 feet from 500 lambs submitted from six slaughter houses. Each foot was scored according to a 0 to 5 scoring system, where feet with score ≥2 were defined as having footrot. Moreover, samples from feet with footrot were examined for Dichelobacter nodosus by culture and PCR. Results The prevalence of footrot at the individual sheep level was 5.8%, and Dichelobacter nodosus was found by culture and PCR in 83% and 97% of the samples from feet with footrot, respectively. Some minor differences in geographical distribution of footrot were found in this study. Conclusions In a national context, the findings indicate that footrot is fairly common in Swedish slaughter lambs, and should be regarded seriously.

    Gender nonconformity refers to the extent to which a person's gender identity, gender role and/or gender expression differs from the cultural norms prescribed for people of a particular sex, within a certain society and era. Most data on gender nonconformity focus on the prevalence of gender dysphoria (which also includes a distress factor) or on the number of legal sex changes. However, not every gender nonconforming individual experiences distress or applies for treatment. Population-based research on the broad spectrum of gender nonconformity is scarce and more information on the variance outside the gender binary is needed. This study aimed to examine the prevalence of gender incongruence (identifying stronger with the other sex than with the sex assigned at birth) and gender ambivalence (identifying equally with the other sex as with the sex assigned at birth) based on two population-based surveys, one of 1,832 Flemish persons and one of 2,472 sexual minority individuals in Flanders. In the general population, gender ambivalence was present in 2.2 % of male and 1.9 % of female participants, whereas gender incongruence was found in 0.7 % of men and 0.6 % of women. In sexual minority individuals, the prevalence of gender ambivalence and gender incongruence was 1.8 and 0.9 % in men and 4.1 and 2.1 % in women, respectively. With a current Flemish population of about 6 million, our results indicate a total of between 17,150 and 17,665 gender incongruent men and between 14,473 and 15,221 gender incongruent women in Flanders.

    Full Text Available This study reports the prevalence of malaria caused by plasmodium between genders in Abeokuta, the capital city of Ogun State located in the forest zone of southwestern Nigeria between January 2002 and December 2004. Blood film examination for malaria parasites in 708 patients; 366 males and 342 females. Microscopic examination of thick films techniques was employed for this study. Of the 708 (100% patients examined, 577 (81.5% were Plasmodium-positive. A high malaria parasite prevalence rate of 81.5% was noted in this study. Female subjects were more infected (42.4% than males (41.9% however, there was no significant difference in the sex of the subjects studied (p=0.05. A high malaria parasite prevalence rate of 86.9% was noted in samples collected in year 2003 than in other years studied. There was significant difference in the years under study (p=0.05. This study shows that a good percentage of people were infested by malaria Plasmodium. This could be attributed to lack of adequate accommodation and poor sanitary conditions in the area under study. Although several efforts have been made to effectively control the high incidence of malaria in Nigeria, these have been largely unsuccessful due to a number of reasons such as irrigated urban agriculture which can be the malaria vector’s breeding ground in the city, stagnant gutters and swamps in our environment where mosquitoes breed in millions, and lack of political will and commitment of the government in its disease management program, low awareness of the magnitude of malaria problem, poor health practices by individuals and communities and resistance to drugs. Therefore, future interventions in Nigeria should be directed toward controlling malaria in the context of a moderate transmission setting; thus, large-scale distribution of insecticide-treated nets or widespread use of indoor residual spraying may be less cost-effective than enhanced surveillance with effective case management or

    Saudi demographic composition has changed because of increased life expectancy and decreased fertility rates. Little data are available about health conditions among older adults in Saudi Arabia, who are expected to represent 20% of the population by 2050. The study aim was to assess the prevalence and risk factors for chronic conditions among older Saudi men. The sample pertained to 400 men (age ≥55 years) from Buraidah, Al-Qassim. Research assistants recruited participants in all the mosques from the randomly selected neighborhoods (16 of 95). They administered a structured questionnaire that assessed self-reported disease history (heart disease, hypertension, diabetes, asthma, gastric/peptic ulcer, and cancer), and medication use; participants' height, weight, blood pressure, and random blood glucose (glucometer) were measured. Multinomial logistic regressions were employed to assess correlates of number of chronic diseases. The mean and standard deviation for age and body mass index (BMI) were 63.0 ± 7.5 years and 28.9 ± 4.8 (kg/m 2 ), respectively. 78% (77.8%) were overweight or obese, 35.0% were employed, 54.5% walked daily, 9.3% were current smokers, and 85.0% belonged to the middle class. The prevalence of hypertension, diabetes, heart disease, asthma, ulcer, and cancer were: 71.3% 27.3%, 16.4%, 9.7%, 8.9%, and 2.0%, respectively. Of the participants, 31.0% had one, 34.5% had two or more, and 34.5% did not have any chronic diseases. The likelihood of chronic diseases increased with increased age, higher BMI, and current smoking. The chronic disease prevalence among the Saudi elderly men is substantial.

    Anosognosia is a disorder that affects the clinical presentation of Alzheimer's disease (AD), increasing in frequency with the evolution of AD. The objective was to determine the prevalence of anosognosia and analyze the associated factors and predictors. Multicenter transversal and observational study of 345 AD patients. Anosognosia was assessed by Anosognosia Questionnaire-Dementia and the evolutionary stage with the Global Deterioration Scale (GDS). Tests used were Mini-Mental State Examination, Disability Assessment for Dementia and Neuropsychiatric Inventory to assess cognition, functional status and neuropsychiatric symptoms, respectively. We adjusted linear regression models to determine the associated variables and binary logistic regression (RLog) to identify predictors of anosognosia. The overall prevalence of anosognosia was 46.7% (95% confidence interval [95% CI] 41.3 to 52.1). The prevalence in stages was 28.4% (GDS 4), 64.6% (GDS 5) and 91.4% (GDS 6). The RLog identified as predictors older age (odds ratio [OR] 1.04; 95% CI 1.01-1.09), lower functional capacity (OR 0.96; 95% CI 0.93-0.98), lower cognitive level (OR 0.9; 95% CI 0.88-0.99), and greater apathy (OR 1.1; 95% CI 1.03-1.18), disinhibition (OR 1.2; 95% CI 1.09-1.50), irritability (OR 1.1; 95% CI 1.09-1.50) and motor disorders (OR 1.2; 95% CI 1.09-1.50). Anosognosia increases with further deterioration. In patients with a mild impairment, predictor variables were apathy, disinhibition and motor disorders. Copyright © 2013 Elsevier España, S.L.

    The purpose of this research study was to determine the factors influencing peripheral phlebitis in the adult medical-surgical population. The authors would then be able to use those data to determine whether a change in practice was warranted. Data collection and analysis of 188 intravenous sites revealed that females with higher doses of medications in intravenous sites of longer dwell times and suboptimal nutrition were at greater risk of developing peripheral phlebitis. The point prevalence was greater than the recommended 5%, which led the authors to review their facility's patient care and documentation practices.

    From January 2007 until June 2008, 504 reptiles of four families and 57 species were examined for Salmonella by using cloacal or intestinal swabs. Salmonella was identified in 139 (28%) of the 504 animals tested. Of the 504 reptiles examined, 210 were captive and 294 were wild. Ninety-eight (47%) of the captive reptiles were shedding Salmonella at the time of sampling. In contrast, only 41 (14%) of the wild reptiles were shedding Salmonella. The higher prevalence of Salmonella in captive reptiles was statistically significant (Preptiles in Australia are not natural carriers of Salmonella and that diet and captivity may influence Salmonella excretion in other species.

    Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p=0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic

    Anecdotal evidence suggests that the sensitivity and specificity of a diagnostic test may vary with disease prevalence. Our objective was to investigate the associations between disease prevalence and test sensitivity and specificity using studies of diagnostic accuracy. We used data from 23 meta-analyses, each of which included 10-39 studies (416 total). The median prevalence per review ranged from 1% to 77%. We evaluated the effects of prevalence on sensitivity and specificity using a bivariate random-effects model for each meta-analysis, with prevalence as a covariate. We estimated the overall effect of prevalence by pooling the effects using the inverse variance method. Within a given review, a change in prevalence from the lowest to highest value resulted in a corresponding change in sensitivity or specificity from 0 to 40 percentage points. This effect was statistically significant (p disease prevalence; there was no such systematic effect for sensitivity. The sensitivity and specificity of a test often vary with disease prevalence; this effect is likely to be the result of mechanisms, such as patient spectrum, that affect prevalence, sensitivity and specificity. Because it may be difficult to identify such mechanisms, clinicians should use prevalence as a guide when selecting studies that most closely match their situation.

    Social phobia may seriously impair the functioning of affected individuals. It is frequently associated with other mental disorders. To estimate the co-occurrence of social phobia with major depressive disorder (MDD) and to analyze their interaction. Subjects were 18,980 individuals, aged 15 years or older, representative of the general population of the United Kingdom, Germany, Italy, Spain and Portugal, who were interviewed by telephone. DSM-IV diagnoses were made with the Sleep-EVAL system. The point prevalence for social phobia was 4.4% (95% confidence interval: 4.1-4.7%) of the sample. It was higher in women (odds ratio: 1.6) and decreased with age. MDDs were found in 19.5% of participants with social phobia. Co-occurrence of another anxiety disorder was high and increased when a MDD was present (65.2%). The odds of developing a major depressive episode 2 years after the appearance of the social phobia was of 5.74. Social phobia is highly prevalent in the general population. It increases the risk of developing a MDD and has a high comorbidity with other mental disorders. Social phobia is often present in the course of depression, more obviously during remission period of MDD. Physicians must explore and treat more systematically this frequent pathology.
